    I use a homemade 49:1 UNUN and 130ft of wire that is hooked up over the top of a pine tree. The wire goes vertically up the tree before bending at about a 35 degree angle and terminating atop a fence post. I do not use a counterpoise but I ground the UNUN to an 8 foot ground rod for lightning protection . I have worked many European stations on 75 meters with both CW and 75 SSB. I have also worked all over Europe and some stations in Africa as well as VK's and ZL's on 40 meters, 20 meters and 15 meters. 10 meters also works fine. I run a maximum of 100W with an Icom -7300 as well as running QRP. I seriously doubt is there is a simpler antenna than a HWEF that works as well, N2SN.

    While researching videos on the Tennena 49:1 I came across this video and was impressed with the performance of the 20 meter HWEF, so much so, I believe I can try this out in may small backyard. I have the DX Commander 10 meter pole and I just ordered the Tentenna 49:1 Unun today. Thaks Walt great video.

    I took my 991a on vacation to the Gulf this year with an efhw... great experience.. I strung my wire from the vacation rental house (with the owners permission) to a pole about 140 ft away.. had some great contacts all over the western hemisphere. We made a video ourselves! Anyways if you haven't done this on vacation, do it!

    I used a TennTennas 49:1 to do my first POTA activation with no counterpoise. So easy to have just a single wire and we activated the park (10 contacts) within the first 20-30 minutes only running about 30 watts. I'm going to have to bring it to the beach this summer to try some DX.

    What is the actual length of the 20 meter wire you're running? I have a QRP Guys antenna which I use 28 feet of wire for 20 meters and I have two 66 foot end feds - 1 I use for my home station - and the other one for POTAs - both with 49-1 baluns. The 66 footer is resonant at 40, 20 and 10. You can't beat them.
    By the way - nice video - great to see VA Beach. As I mentioned in a previous note, I was stationed at Portsmouth Naval Shipyard back in the late 60s and we used to head to Virginia Beach when we could.

    • @COASTALWAVESWIRES
      @COASTALWAVESWIRES  2 ปีที่แล้ว +3

      I believe the length was 32’-9” which is a true half wave around 14.280. I think I will try the 66 foot length down by the sea wall here in Portsmouth. Thanks for watching and 73 from your old stomping ground!

    Great video....amazing to me that little 5% counterpoise does much but hey who knows......Did you try it without the counterpoise? I would think that your coax shield was the main counterpoise. Love your channel.

    • @COASTALWAVESWIRES
      @COASTALWAVESWIRES  2 ปีที่แล้ว +2

      I actually didn’t try it without the counterpoise. I did a bit of research before building that antenna and found several places suggesting the 5% counterpoise. I actually tried a longer one at five watts QRP with the QRPGuys EFHW and tossed it because it ran my SWR up higher. I used that EFHW without a counterpoise and had good results. There’s a video of it on my channel. Thanks so much for the kind words and watching. 73, K4OGO

      Honestly this one is a close second to the Vertical Random Wire I did with the Nelson Antenna UNUN and that’s only because they were both multiband. As far as true DX the speaker wire quarterwave vertical I did for 20 meters was the best performer because it was truly resonate but it was limited because it was one band. Currently I’m really digging this Slidewinder Coil setup I’m using because I can get it up and down so quick and I don’t need a tuner when operating.
