An Easy Build Guide for A 49:1 EFHW Antenna!
HTML-код
- Опубликовано: 5 мар 2024
- The video is geared towards you if you are building a EFHW kit with a 49:1 Ratio.
An Easy Assembly Guide for a 49:1 EFHW (It doesn't even need to be this kit). The kit I use will get 4 bands (40,20,15.10) if wrapped this way.
If you did not buy the HRD Industries kit, most of this stuff still applies.
This does not include any other instruction except the actual build. Antenna wire cutting will come later. I have confirmed this antenna and build to acquire 4 bands. I'll have charts and stuff later.

Just want to make one quick note: somewhere around the middle/end of March, the wire was swapped from Kevlar wire to DX-WIRE UL (www.dx-wire.de/dx-wire-antennendraehte-litzen/dx-wire-ul/) Vectran Wire. This still allows for great strength antenna wire, but I was able to reduce the cost of the kit by purchasing this wire. I'm always interested in suggestions for future wire use in different kits. ****Kits are currently not available until appx June 2024****
Bought it, built it, tuned it, used it on a POTA got the longest contact in my logbook of almost 10,000 miles! My FT710 can tune on 10m. No tuner needed across all of the other 3 bands! It is my new go to for POTA. I put the feed point on a 15 foot mast and stake the end in the ground. AWESOME! W2UWK 73
I love hearing stuff like this! Nice and thanks for sharing! Yesterday, I took a tech out and his first contact with the antenna was (if I recall correctly) France and Spain. Too easy. It's the winders, I added some 10dB mixture to them :D
Good job Sean. I would probably use another screw and wing nut for the antenna wire instead of soldering. Makes it easier to repair in the field when the wire breaks.
You could definitely. It considered my mind also. Hardware is cheap at the store. Also could be made into a fan dipole the same way. Cheers.
Great suggestion, actually. I am out of kits now. I should have more supply in the next week. However, because of the amount I ordered, I got a discount, which should allow me to add the extra set of hardware in, for the choice of the builder.. Take care.
I can't wait, just bought one.. thanks, and keep em coming.
Well done and nicely presented. Thank you.
Looks like a nice kit 👍
Great job Sean! Keep it up and do what you do!
Thanks! Will do! take care, aloha.
Gonna test mine today.
Awesome. Feel free to shoot me an email with any questions. Thanks and enjoy
Thanks!
Thank You!
i need one!
Looks like there is about 3 kits left this morning. There will be a delay after that while I await a new shipment of wire.
Does the sticker include spicy ketchup? Nice build guide, Dude.
Maybe you mentioned in video, but I missed it. What gauge of magnet wire are you using there?
22 gauge. It's been good for 100w on ft8 digital for an hour at a time. I'm thinking about beefing it up to 18. That will definitely beef it up more. What are your thoughts
I just picked up some 18. I think I used 16 on another build a while back. Wasn't too hard to wrap.
Do you sell these fully assembles: I am partially blind and will never be able do do this correctly
I can do that. Reach out to me and I'll be happy to figure out all the details. Thanks.
Nice build demo. Wouldn't it be better to place the ground lug between the hex nut and lock washer, and then screw the bolt tight, thereby squeezing the ground lug between the bottom of the hex nut and lock washer? Then the wing nut will fit tight against the top of the hex nut for connecting the counterpoise. Just a thought. 73 Ken -- WBØOCV
Once you fit the fork connector in there, there's no issue.. cheers
I just re read this. Yes that'll work! Thanks
The cooling fan is sucking out the air or blowing in? I'm confused about the direction it should be on my go box. Please help!!!
Is this in reference to something on this video? If so, please link me a time stamp. Thanks.
when will this be back in stock? I have checked multiple times. 73 NS9T
10 weeks or so. There is a delay on the toroid's and no companies have them, unfortunately (Except the ones that mark them up). Thanks!
@@HAMRADIODUDE anxiently awaiting...thanx
What toroid is that?

Looks like you’re using the “new” 2463251002 torriod. Not the 140 or 240 43 mix. Just bought several to try. Seen some videos where it gives you about 10-15% more efficiency especially at the higher frequencies. Hadn’t seen a kit come with one yet.
Well up in the air but liking that it is kevlar
