Hi Paul, It was great to work you again , nice video! Thx ON2WIM '73
Yes, my pleasure Wim! Thanks for the nice report :-) Hope to hear you soon again and Happy new year! 73, Paul
Hi Paul,
I enjoyed watching your build and the test of the MicroVert antenna .
You also have very interesting other topics on your youtube channel.
Thank you for sharing.
I wish you and your family a blessed and healthy new year.

Hello Bernd! Thank you very much for the kind comment. I am very appreciated it. It giving me a more motivation to making videos like this ;-) Happy New Year, be healthy and have a prosperity in 2019. 73 Paul :-)
Very nice job, Paul. Nice antenna. 73 and HNY 2019
Thank you very much. Happy new yaer to you too 😉🍻
Very nice results, thank you for the footage. 😊73
I use it now as my base antenna for 40m band - until I will hang the endfed antenna ;-) 73 HNY 2019
[0:41]Yes it will effect both antenna`s
Wow man congrats a nice short antenna awesome performer. Thanks for sharing happy new year
Thank you for watching Eduardo! And Happy new year to you too! ;-) 73
Nice job with the antenna and great video. 73
Thank you very much Gerry! 😉👍 73 Paul
A well -performing little vertical. I may have to build one! Thanks for your videos.
You are welcome! 😉👍 You can use 100W with this antenna. But don't forget that one part of the coax radiates too 😉. 73, Paul

Thank you John! See also the calculator for good planing of your next antenna and good luck with it. Let me know how it's work please. 73 HNY 2019. Paul
Brilliant!
Brilliant video. Congratulations. You are extremely high up. I am curious how this would work mobile or very low on the ground level. Thx
Hi Chris! Thank you for the kind words :-) I tryed this antenna only from my window with QRP 5W and I had couple QSOs, but I never tryed it from the ground level. Happy new year! ;-)
Thanks Paul for the two videos. I'm surprised of the antenna performance as shown in the video. The SWR plot looked like a dummy load connected to the transceiver. The flat SWR probably indicates heavy losses on the radiator. I suspect most of the radiation efficiency comes from the coaxial counter antenna, which reminds me a similar set up to the T2LT antenna. However this a good solution for hams with restricted space. I wonder what will be the difference using a larger radiator for example a 2.5 meter long whip, which is still a decent size using a fiberglass pole or and ld CB vertical. I also wonder if there is any improvement making a 4 to 5" diameter coil that will exhibit a higher Q, with a better and "healthier" resonance. My guess is in set up show in the video will achieve the best performance with the coaxial line up to the choke as straight up and clear from clutter as possible as this is probably where the antenna efficiency comes from.
Nice....
Paul, very nice experiments! It would be interesting to know the reactive (imaginary i.e. capacitive or inductive) component of the antenna measurement too. Also, how does the received signal compare to the spiderbeam?
Hi Jan, thank you for you comment. Sorry but I don't have real antenna analyser yet. Can you recommend me one? Shouldn't be too pricy of course :-) HF range only is OK. On my HEXBEAM antenna is not a 40m band segment so I can't do real comparison. I can hear clearly 40M band signals on HEXBEAM but antenna is not tuned and of course is not capable to compare. But i plan to hang 45m long end fed antenna from my building to other so after that i will be able to do comparisons :-) 73 and Happy new year!
now that's a real radioamateur, he builts antennas despite beeing cold and shaking from the cold weather.
Is the SWR affected when you have a full load of washing on that clothesline??
Neat work as ever. How might this compare with just putting a 1:1 balun in the feedline with your Moonraker spx100 ? Perhaps do a direct comparison of the two comparing results of station readings of signal strength on RBNet - would be a bit less subjective ??
Thank you very much! :-) Comparings on HF are still questionable because of different phasing, polarity or QSB between two different antennas and due to different ionospheric refractions or paths. But just for approximate comparison is should be good. The 1:1 balun is not much neccessary to use on Moonraker due to different design of antenna. ;-) 73 Paul
Poland welcome 🇵🇱 AWESOME 73
Excellent video once more. Congrats! Though I am still wondering if this antenna would be capable of a really big DX, like Japan, or Indonesia, or Australia, or South America. I do want to try and make an antenna of this magnitude, cause I am in very difficult QTH. I have neither enough height, not open space. If you have something like this in your plans, it would be great. Congrats again!
Hi. I am able to compare this antenna with 20m band dipole only and results are clear. I receive DX stations stronger on 20m dipole. But MicroVert antenna is lower than dipole, has an opposite polarization and almost complete radial wire is hided at the elevator room. So I think that it is not very fair-play comparison. I believe if MicroVert was located on the the high rod and it's radial wire was hangt vertically down from antenna in open space so I am sure that it could be as good as the dipole is. If you have a space problem so try to made a magnetic loop antenna with remote controller. You can use a vacuum variable capacitor and thick copper tubing feeded with gamma match. In vertical plane is this antenna directional and in horizontal plane omni-directional but with less gain.
Hello Paul. Part 2 of the build of this antenna is amazing as you say. We often think that a compromise will not work. Why? Because the theory says it shouldn't or maybe some of our friends are the stimulus for that doubt. Then you try using the antenna and find that it does work. I think you said it correct in your first video that you would not depend on this antenna for decent DX but sometimes it might work decently if band conditions permit. Best 73 es HNY de KB8AMZ
Hi Terry, yes I agree with you. Hamradio is so nice hobby right because of small miracles like this when you will made own small home made antenna and will put it on the roof, tree or tripod and with just a 5W you will get some good contacts. That's my happiness times with radio hobby. There is no doubt that big beam antenna will work properly and will be efficient but I am more happy when I make a QSO with QRP radio and small portable antenna :-) Many HAMs has telling me that magnetic loop, EH or shortened verticals are a small unefficient antennas and there is no reason to made them. But sometimes it's the best way how to work with radio when I am outdoors for instance or in this case when I don't have better bigger antenna for 40M band, it's better that nothing and it's still working fine I found out :-) 73 and Happy new year!

OK! Very nice! US7ITC 73.
Thanks :-)
I recently homebrewed a similar antenna. I have an swr of 1.7 the balun is capable of 450 watts. Driving with 10 watts from the 7300 gives 110 watts using a sailor marine amplifier. I get 250 watts on my inverted V on the same setup with 2.0 swr. What's wrong with my antenna, any clues. Thanks
you will have a lot shielding from the nearby other antenna,s...
Hi paul can you tell me where you got the micro vert antenna please.
Great video.

Very nice! You have a link to constructing it?
Yes of course. Here in this my video: ruclips.net/video/gpRv6LqKlbw/видео.html
Amazing antenna. I want to test it on 20 m band
Yeah, tryed it. Tuned by SWR = 1 all ok, but can't recieve anyone. Also I finde some clarification about microvert antennas: real radiator is cable shield, and whip actualy is counterweight.
I am working on a small antenna wire 7.5 meters long and a tuner icom AT-130 at 160 m. band CW ranges over 4000 km. :)
73! from RX9JC op.Ven qth Surgut
think of a EFHW antenna, shorten kind, will be 4 bander at least ; loads of info on the web.
9k2oD use huge antenna... that padu !!!!
I'm recognize your voice! I'm heard you at 14MHz band a month ago! My receiver: SANGEAN ATS-909x; antenna: a piece of long wire under the curtains; QTH: Arkhangelsk, north Russia! 73!
Very nice! I don't get many SWL reports from listeners :) Thank you! How strong and readible was my signal please? ;) 73, Paul.
Paul, the signal was very weak, but voice was fully legible! Built-in S-meter shown nothing! 73!
@@ivvitan aha thank you for the report! I am glad that you heard me even so far away on just the piece of wire 😉👍If you will hear me again please let me know 😊 73, Paul.
Quick question.. are the elements insulated from each other ?
No in my case.
How did you get the Multi Function Meter with Power please? At 7.47 on video. I can't find how to get that display.
Sorry Paul - I thought you were using Icom 7300.
Hello Keith. The Multifunction meter you can get very easly. Just push the MENU button and select METER on the touch screen. ;-) Paul
Thanks Paul
@@keithwinkler736 you are welcome Keith and Happy new year! ;-)
Hello Paul
Have a queustion about bulding video. I have buld a micro vert for 20m by your video I think I missing something.
Have I have tp use a capacitor to for reonance the antenna? Caculation program You use seems no good.
pls anser. But Your Video are great.
Hello Hendrik, what exactly is wrong with your antenna?
@@OM0ET Hello Paul, I build a 20M Microvert by the microvert program. Only with other demensions. All Other parts as coax where the same size. But the SWR was high above 3.(5 and more) What if I use a cappacitor in serie with the coil. And is this neaded? My Call PD2HPS on qrz.com

Thank you Panos 😉👍 and Happy new year!

Hi paul. Love this antenna. Looking for a portable antenna to work from the beach along side my x5105 qrp transceiver. Dont suppose you make and sell them ??? Cheers m6osd

@@OM0ET thanks for the reply. No problem i understand in regards to the copyrights. Would of been very interesting to see the results from the beach. Neva mind 🙁. But if you ever want to send me one to try i would happily make a donation to your channel haha😉cheers.
@@m6osd217 that's a great idea Scott 😄 😄🍻 ... deal
Consider an EFHW antenna, they are easy to use /p
@@W-733_KWX cheers. I use a 1/4wave 20m wire up a pole as a vert . Works well but i am looking for something small and simple. Dont like having to take poles or throw wires up trees. I live right on the northeast coast so want to be able to grab minimal equipment and sit on the beach 👍 also been looking at the whizz loop.
nice project - fine job. congrats! 73 fredy HB0BB
Thank you very much and Happy new year! 73
l like the antenna,i need to bulid one please teach me sir.
Thanks! 😉👍
NICE JOB POUL(i'm gona macke iz too for sore!! 🤓All the best from Slowenia🇸🇮73 i don't have a place for some"real one"BIGER antenna" like a beem..soo..I NEED SOME SMOLLER FOR A BALCONY🥲🥺😢🇸🇮**Any advice more?
If you dont need it any more...hmm can i ... 🙂
My LW antenna broke under heavy snowfall, so maybe I will use it again :D hi
I figured you would use it for portable and not for home use.
Yes. But this time I don't have any other antenna for 40m band. I plan to hang 45m long endfed antenna for 80 to 10m bands. Then I can use it for portable purposes. 😉
@@OM0ET I use a homemade EFHW 80m-10m antenna for at home and another for portable, they work well with my IC7300 and X5105.
Steal bather then nothing WTF? My friend?! Its cool antenna😉
Hi Paul, nice video, as usual are all your videos.
I would report tonyou that the download PDF doesn't run☹️.
