- While I didn't film me making it, here is a quick video of how it turned out. It is 140 feet of DX commander wire doubled back to about 137 feet and tied off to a rope and stretched between two trees in an inverted L.
I just added a remote relay to my efhw to bypass the balun. And gives my 1/4 wave on 160 meters at a 1:2 to 1:5 swr on entire band.
I would love to hear more about that.
@@Blackabeard just run your coax to the antenna wire bypassing the balun. You can also do it with a relay mounted in a box and trip it with a direct wire or use a bias-t to run it through ur coax
Where can I get a remote relay?
Your next step should be to take an antenna analyzer to see what the SWR looks like. You also need to take into account the four turns you have on the cutting board as it's forming a base loading coil for the antenna along with providing strain relief. I'd also suggest you add some sort of lightning arrestor, like one from Alpha Delta. Just a strong wind and rain can generate a lot of static electricity on that long wire in the air. If you have room for a couple of 131-foot radials you could raise the feed point up about ten feet and have the radials coming down to the ground in an inverted "V" configuration. Elevated radials are more efficient than ground mounted radials.
Thank you for the thought on the radials. The analyzer showed it was pretty flat. The SWR was low enough at 1926 that my internal tuner would not even move it. I do need to work on it this year some so I will look into the radials. Thanks for watching.
Is so annoying sometimes that we find a nice corner in the house to build a nice shack.. then we don't have an easy way to pull coax in )). I love how much space you have for antennas. My garden is a bit strange so I can't put anything longer than 40m of wire )). For the same reason... hard to bring coax in, the easy and cheaper way. 73, YO6DXE. I subscribed cause you have the beard I wish I had but it just won't grow hahaha.
Thanks for the follow. The beard is a blessing and a curse. Hot in the steamy summers we have. But I had to be clean shaven for most of my life. Now that I don’t I love my beard. Also the yard is great. I wish I had one tall tree. But the tower will go up soon enough
@@Blackabeard Ohh I hear you with the tree. Same problem here... I used to have one and it was so good for antennas. Sadly it was old and I had to cut it down. Now I use a wooden pole but is not as high. About the beard... yep... that is why I want one haha.. I had to be shaven all the time for the jobs I had and I hated it haha. Now I can grow the beard but it seems all I have is Jack Sparrow beard not Blackbeard 😅 . 73 buddy and have an amazing rest of the week.
Excellent Job done...73 de Uncle Günter 👌🙋♂
Thank for the kinds words.
I’d stick a 49:1 transformer unun on that. Should work great on 80, 40, 20, 15 and 10m as well.
For sure. I use a 49:1 and 67 feet of 16 gauge speaker wire normally for my portable operations.
Hey Justin. How does the 160m antenna work for you?
It’s doing good. It took some damage over the summer but it’s on the air and still doing well. SWR has come up but is still under 2:1. Thanks for watching.
Look forward to seeing it on the air. No UnUn transformer? I’ve looked at an 140’ EFLW, end fed long wire for 160m but haven’t done it yet, but uses a 9:1 UnUn. Look forward to some test results.
Not one thing other then some RG-8X. It’s flat at 1:1.1 across the entire band. I have it doubled back to about 137 feet and works well. Once the band opened again this weekend I was able to make some great contacts.
@@BlackabeardI don't understand how that's working. I attempted a random wire antenna once. Damn near burned up my manual tuner. The impedance is much higher but you also said it was an inverted l with radios. Even then the impedance is much higher than 50 own I don't know how you're getting a match. Very intrigued I'm working on getting up of 160 m dipole. Need to talk to my neighbors though because I don't have enough real estate
I have a very little knowledge about it. I still think SWR and propagation is all black magic and voodoo. It all confuses me. I read The Wire Man book on long wires and it seemed like it would work. Threw it together and boom it worked. Luck or skill ill take it. It's very flat at 1-1.5 : 1 SWR. Most of the time my if needed the interns; tuner on ,y Yaesu FTdx-10 can handle it. Good luck getting yours on the air. And hopefully your neighbors will let you string some wire on their trees too.

@@Blackabeard thanks brother.
