I love making all my antennas. Just finished a EFHW 67' - 10, 15, 20 and 40m sloper with a 49:1 auto transformer at the feed point. Works great without the ATU in the FD-450D but I uses the tuner to touch it up. 73's KN4IFI
Joseph Rostochak excellent!
Hi Ray...nice tutorial...it was a pleasure to listen to someone not full of their own self importance for a change. Thank you.
A good, basic, informative tutorial on vertical antennas. Ray (G4NSJ) does an excellent job of explaining a complex subject. I use both verticals and dipoles for my ham radio adventures. Both antennas are useful, depending on what propagation is to your DX location. I like Ray's "down to earth", casual explanations. Aloha es 73 de Russ (KH6JRM),
+Russell Roberts Hi Russ, thanks for that. It's nice to get feedback. Cheers, Ray.
Have to agree Russell.....Ive learnt a thing or three......For instance I no longer use 50ohm coax as a feed to my dipole....Ladder line is much better!....
Thanks for the reply, gripper. I tend to favor ladder line or television twin lead for my HF antennas. With ladder line, I can get several bands from a basic dipole. A great tool for those of us having limited space. Aloha, Russ (KH6JRM).

Hi Russ. Well after watching Rays excellent video I have binned my 40 mtre coax fed dipole and managed to fit about 112 feet of wire in a dipole configuration, 56 + 56 or near that anyway, got myself a MFJ-948 and some 300ohm and I couldn't believe the results, absolutly brilliant, Ive always had verticals, mainly due to having small garden but have a large garden now so was able to do this....I'm really glad I found rays videos, I can listen to him waffle on all day cos he makes it easy to understand and it certainly isn't boring like some vids about antennas etc and I have learnt stuff too.......73 M6KQL Mark
What a great narrator! A great bunch of people Radio Amateurs are, committed in helping others by sharing ideas.
Thank you so much Ray and happy DX ing!

Thanks for your comment, it's nice to be appreciated. Cheers, Ray.
@@g4nsj IF I use a dipole or doublet why is it i can talk to people from russia cananda and south american then
Andrew Murphy Not sure what you mean. Probably because it’s a good aerial.
@@g4nsj you said that dipole was only good for loc are like london and etc.But i am telling u the doublet and dipoles i use i have talk or hear almost around the world like canada, oslen norway, ausstraila etc. so saying that they are not good for long distance qso to point your right but there aging i have better luck with dipole for dx etc
@@AndrewMurphy8383
I think, in Ray's situation, he's at the bottom tip of England so, if his wire dipole is stretched E - W, his radiation lobe is N - S and so, as he says, he covers all of the UK due north of him (..and of course, anything south of his location).
The vertical on the other hand transmits over the horizon which, again as he describes, gets to do DX contacts while, depending on *terrain* can easily miss close receiving stations that are not located up high. And the higher the gain of the vertical antenna, the narrower becomes the transmission lobe. This is more evident on higher frequencies.
Anyway, with your (wire?) dipoles, you can easily get long DXing _on the tranmitting lobe of the dipole_
And of course, if you use more than one dipoles with different polarization ( N.- S.) or ( E - W), then yes, you can work the world as you do! 😉
Another great Video Ray.
Thank you for your time.
Ed Wymer thanks Ed!
a joy to see another OM haring his knowledge with other hams,wish there were more like you,,,regards gm7jds
good ray, built that 20m vert a couple of years ago off your site.got my 20m dxcc award on that antenna over 200 countrys worked 0n 20m vert at the moment.keep up the good work.73 dave
Hi Dave, that's good news. I'm so pleased that the aerial has worked well for you. Thanks for taking the time to comment. Cheers, Ray.
I wish you were my neighbor. I am starting out and trying to learn as much as possible. You have provided some practical real world information which has helped me connect some of those loose puzzle pieces that have been rattling around in my head.
thank you. I have subscribed and hope to learn more. .
spy8464BB Hi, I'm glad you found the video useful. More coming soon. Cheers, Ray.
Just good advice and no bull ,and it makes sense more vids please Joe
Thanks, Joe. More videos coming soon. Cheers, Ray.
Thanks for the explanation Ray. I enjoyed your description. It helped me to visualize the radiation pattern on a vertical.

A friend of mine who is a broadcast engineer says that it is crucially important for ground radials to be arranged symmetrically. If you can only arrange two radials symmetrically, then just use two.
Ideally the ground-radials should also be several feet above the ground (which in many situations will not be practical).
Thank you, after huge amounts of study on the subject the "penny dropped". I will be forever grateful. Take care, David
+David Harper Thanks, David. It's nice to get positive feedback. Cheers, Ray.
Ray,
Thanks for the GREAT Presentation!
You’ve given me an idea for making a 20m Vertical Antenna!

Hi Bill, let me know how you get on with the aerial. Cheers, Ray.
Your vid gave me a great idea for setting up an aluminum vertical and using it as a support for an inverted-V dipole. Best of both worlds. Thanks!
+combatjm89 Good luck with the aerial. Cheers, Ray.
Hi Ray. Just to say how much I am enjoying your videos. It has put many ideas into my head regarding vertical antennas. The one I have made and still working on uses a garden table plastic leg for the garden wire coil. Car brake pipe as vertical telescopic rod. Stand for aerial is a cheapo selfie stick like tripod. Loudspeaker cheapo wire for ground, counterpoise etc. Ìdea is for portable use when out camping or motorhoming. If you have some spare time have a look at my videos if you can find it and your comments would be greatly appreciated. Ps my Hobby used to be Stationary Engines. I used to own 27 Engines. Cheers from old George Petter
Hi George, I’ll take @ look at your videos when I get a minute. OK on the engines. I hope to get my Lister D running this year.
I loved the snippet about bending the mobile antenna over for NVIS
Great thanks, as Theo T said you answered a lot of questions before I had chance to ask......Top man......
Thanks again Ray, another relaxed mix of knowledge and humour, wish my science teachers had been this interesting, and "Radio Theory" in the Army was described by one wag as Mystery Hour !
cheers Dave
+David Chadwick Hi Dave, thanks for your nice comments. I'm glad you like the videos. Cheers, Ray.
Hello Ray. I have a vertical antenna for 20metres - basically it is an old CB antenna with the coil removed. It has no radials - yet I have had good signal reports from Russia - Bulgaria - Romania - Italy etc. I adjusted the length to exactly 5 metres and it tunes using my MFJ ATU. It is sort of grounded as my Transceiver is grounded to an earth stake in my lawn.So the antenna is a Quarter wave vertical for 20m and a Half wave vertical for 10m. I live in Towcester Northamptonshire.
Hi Frank, sounds good to me. I love verticals. Get some radials out soon. Cheers, Ray.
Thanks Ray - Hope to get the radials done tomorrow. Just have to experiment don"t we. I love it . Cheers.
Thanks, Ray. Food for thought. All the best.

At 19:39 = put your seatbelt on.
One should have a vertical and a horizontally polarized antenna for all situations. And don't be afraid to change between the two.
I enjoy most of all experimenting with aerials in my amateur radio activities
Me too, it's the best part of the hobby.
Hello, thanks for your lesson on antennas! Very informative. I have some new ideas for a ground mount antenna now. We`ll be checking out your channel. 73,
Joe KC3BXZ
From my experience, one of the best vertical antenna's is the j pole antenna.
I decided to try vertical instead of inverted v, or mag loop after watching this (very helpful) video. Basically, I think it's a point well made, my vertical has performed far better. 73s.
I'm pleased that you're getting on well with the vertical. They are excellent aerials. Cheers, Ray.
Wonderful as always. Thank you .
Cheers Ray. Cracking and very informative video. Thank you.
Ben 2e0omr thanks!
good video very informative ,,ive been on the 11mtr band for 20 odd yrs plan to do foundation this yr so will be playing around with some homemade stuff myself soon ,,,,bring on the summer ,,cheers shane warks
Bring on the summer indeed! Nice to hear from you, Shane. Good DX. Cheers, Ray.
whats your views on the mfj antenna analyser please Ray ?
To be honest, I've never tried one. However, I have heard that they are pretty good.
One of the best videos I've seen, Ray. Great job.
+Jim Hall Thanks, Jim!
Far more knowledgeable than myself, but without being synical, these very knowledgeable guys don't apprieciate some of us aren't and so want to build something easier. In particular why not tune from the rig end, maybe with a simple UNUN at the verticle base! Brian M6BAQ (QTH Dover).
Ingenious Ray cheers.
Enjoyable indeed ! Thank you !!
Thanks!
amazing explanation...thank you so much, you answered me 20 questions i had....vertical antenna it is...
Excellent, hope it works out well. Cheers, Ray.
Thanks Ray. Interesting and informative as ever !
Thanks Paul.
The Skip Zone is one thing but there's antenna polarity to care about... when it bounces off the ionosphere it doesn't matter as much but ground waves are polarised!
Indeed, there are many factors affecting radio wave propagation. Cheers,. Ray.
The common 43ft Vertical is great as a 5/8 wave on 20 and on a mast (insulated from mast) with down sloping radials (counterpoises) to increase the impedance. Less ground loss and faster than buried radials. "Might" fit your garden area. The elevation also lowers the TOA.
Thanks for that, Don, Interesting stuff. Cheers, Ray.
Good info, and fun to watch to boot!Good stuff! ThanksCheers,Alan
Great stuff, I love antenna experiment, my 60m dipole is only 20 foot high,,,does what it says on the tin! 73 Tony M0RIF
Lots of good points a i am trying to build a vertical .
Thank you for a very interesting video.
I love your natural, relaxed style coupled with the fact that you know what you're talking about.. So many internet-arrogant gurus don't!
One problem which mystifies me. You can't be a proper Ham. Your shack is to neat and tidy. Do think that YOUR XYL could knock ME into shape as well?
Mine can't!
May I just add that an MFJ analyser or a noise bridge, would do the job without radiating a signal?
The noise bridge could be a simple home made one and used with the RX but of course the MFJ would need the money which you wisely try not to spend.
Good to watch. I'll look for more from you.

You’re Right!
Amateurs “Generally” have some kind of a “Rats Nest” near their Radio’s, encompassing the Tuner(s), Amps, Coffee Makers etc...However, I have Yet to meet a HAM who can’t reach out and Touch Whatever piece of equipment that they Want/Need to access at Any Time!
Just discovered your channel. Great video! I shall enjoy watching the others. Liked & subscribed!
Excellent! Tanks for commenting. Cheers, Ray.
What a relaxed informative and funny at times video thanks Ray :-)
+tomcatGB Thanks, glad you enjoyed the video. Cheers, Ray.
Very useful info,watched breathlessly, spare more info about other type of antenna.
Loved the feed Ray 73s Rod 2E0RLR
Roger Hanson Thanks, Rod. Glad you liked it. Cheers, Ray.
Fantastic information, thank you
Thanks!
My horizontal end fed wire works great for inter g and works great for working Australia and all around the planet!! Explain that.
Excellent! Obviously good sky wave. 👍
Very informative video...Thank You! Very fine workshop also!
Thanks, I'm glad you enjoyed the video. Cheers, Ray.
Thank you for the reply!
well explained like watching your videos.
A lot of good, common sense ideas there. I'll keep checking back. N5XV
Thanks!
Tnx Ray, good DX, love verticals. K8OOI.
+Gustavo Bourdieu Glad you lied the video. All the best, Ray.
I have a heathkit receiver and it seems to work best with my 18 foot antron plugged in and a earth wire connected to the earth screw on the back panel the antenna is 10 foot above the hows ridge .Seems to work well Is this ok to do.
Regards nick
Sounds good to me. Well done.
Excellent !!!
Thanks.
Very interesting thank you
Hi Ray, you haven't changed a bit in ten years. Must be someting to do with radiation. How do you terminate the wire at the top of the vertical antenna? Thanks in advance. Love your videos.
Perhaps I’m getting younger, that would be nice! The wire at the top of the aerial just ends. There’s no need to terminate it. Glad you like the videos. Cheers, Ray.
@@g4nsj Thanks Ray De M7AIL.
enjoyed!
tnx for a very speedy responce..regards brian gm7jds
Hi Ray, I fully understand the need for a good earth with radials. However I am wondering how Roger G4ROJ does so well with his vertical kite aerials with only one small rod driven into the ground next to his car. Any ideas? Cheers, Phil, G8RFD.
Phil Short Hi Phil, the need for a good earth depends on the length of the aerial. If the aerial is a half wave, then an earth isn't needed. A quarter wave aerial will need a very good earth system. Cheers, Ray.
Thanks for the good ideas. 73 de KB3UYT.
Hi Ray.. Watched it again for further enjoyment.
Remarkably realistic.
It always rains. How DO you arrange that each time?
73 from G3NBY and WB7MBR Dave in Utah.
Hi Dave, it's al done with smoke and mirrors! Cheers, Ray.
wonderful video . I have a random question about a vintage german ww2 large diameter copper tank antenna . I have a neighbor who collects and told me Hollywood uses those german copper panzer antennas for sword fighting and they do not bend . how is this possible being a soft metal like copper ?
+Jamie Williams Sorry, I have no idea.
could you do a vid on the effects of coax length on swr reading in the shack and odd multiples of a 1/4 wave theary...something thats often overlooked when installing antennas
+battlestarone Yes, it's on my list. The list is quite long but I will get round to it. Cheers, Ray.
Interesting stuff thank you
Thanks. Cheers, Ray.
Love your videos. Question sir. Does a vertical HF antenna with a resonant counterpoise work as effectively as the same antenna with ground radials? Does it affect the radiation pattern? Thanks in advance from a new Ham. KG7VCL.... 73
TheMojo1963 Ground radials are far better. Also, the radiation pattern should be more equal around the aerial.
Hi Ray can this setup use twinlead 300 ohm instead of coax, it appears your coax goes up the guts of the tube, RG 8, then you use RG213 from the tuner.
For a dipole, twin lead is perfect straight to a tuner.
I have a Chameleon V1 I want to put up on a chimney, Distance to shack is around 15 meters. Will RG8 be fine or can I use 300 ohm ladder line. Its hard to find info on this setup, especially how to connect the ladder line to a PL-259 connector, can I use a 2 to 3 inch piece of coax to solder to or will it bugger up the ohms or something.
Help from you or any of your fans would be great.
BTW Thanks for the great videos, your fun guy to watch and listen too...
Grant.
It will probably work with 300 ohm. Give it a go, I've never tried it. Cheers, Ray.
I liked the movie.
Congratulations.
73 YO3DLK-Alex
Thanks Alex. All the best, Ray.
Thanks for all the good info on verticals Ray. Very interesting.
I'd would like you opinion on the K4KIO Hexbeam that I am really interested in acquiring. Do you have any experience with these antennas or know others that have? I'm most interested in DXing, so do you know if this has a low angle of radiation like a beam antenna has?
Again, thanks!
73s
Tom
Hi Tom, I don't have any experience with that aerial but I will ask around and let you know if I come up with anything. I would have thought it good for DX as it's a beam. Cheers, Ray.
Hi Ray
Thanks for great tutorials on antenna is the whole 40 feet the actual antenna or just the top section I'm new to the hobby studying for my licence here in Oz
Thanks again for great videos

+bryant thompson Glad you found it useful. Cheers, Ray.
Have you ever used a real tall vertical like 57ft tall for 20 thru 80 meters.
The longest I've used was around 45 feet. Excellent results. Cheers, Ray.
Hi ray
can you do a video on yor thoughts of a Mag loop please.
