    Great buzzing sound in the background - real atmospheric. I like that you didn't show the VSWR being measured at all. Nice job.

    I have one just like it. Works great on all bands. 73 N5QF Houston👍

    Shortly after filming this, I hit Long Island and Washington state with only 100w.

    Hi
    I have friends in the midwest and most of them tell me that they erect a 160 loop(they hv the space😅), attach an auto tuner and forget the rest. Is this the way to go, if so, do you sell them?
    Thanks

    How do you figure out what length wire you need? Say for 40 meter band

    • @electrolytics
      @electrolytics Год назад

      Feet= 468/MHz. That's for a Halfwave antenna. So divide 468 by lets say 7.200(MHz). You get 65 ft of wire.

    Great , i prefer to trim or bend the excess of antenna wire at the end but i can see that in your case it's easier at the matching transformer , those EHFW are great antennas for limited space ⚡🪐

    Definitely like the clear cover so you can see it working lol.. I'm a bit confused by your statement and posted comment.. You mentioned you reached out with only 100w which is a lot..I've seen North Carolina to Australia on QRP 5w of power..but even more confusing is you mentioned its only for 11 meter band..the CB band which is limited to a maximum of 4 watts total.. Blasting 100 watts on the CB band would be 25x the limit..perhaps you actually meant to say the 10 meter band..Cheers..

      Oh your hilarious! lol Guess you don't spend a lot of time on 11 meters and are clueless about it. Some of those huge guns are running over 100.000 watts off of huge long john beams, and commercial electric service at 400 amps. You way to funny man. "blasting 100 watts" comedy gold, lol

      @@acidreign8551 well US regulations is 4watts of power transmit on 11 meter / CB radio..so 100watts is 25x the legal limit..so yeah its blasting..those 50k to 250k fines start to add up quickly..

      @@agentcovert Since i first keyed up on 11 meters in 1979, your not telling me anything that i or anyone else doesn't know. Go the the fcc.gov website and look it up. A grand total of only 5, count them 5 enforcement actions since 2012, and only two of those were naughty letters to CB operators and nothing more. The other three were naughty letters to GMRS jammers, with no fines actually collected, no equipment seizures, and no operators anywhere imprisoned.
      And so what was your point again?

    Why a auto trans Unun if you only operate 1 band? And howmany watts you run. And how many fars you get. 924 in the diesel car asking.

      Because I do not want a huge beam or omni on my roof. 4watts. I get out really far.

    drive a rod in the ground and just ground it and throw the counterpoise away

    Your SWR is just showing you the wire is a bit long, it's resonant lower than 26.965mHz, maybe around 26.5 or even 26.2mHz, little bit more trimming should bring it down a bit. The toroid is also an issue, close wound one side, wide spacing the other, BAD idea, badly wound. My 49:1 67foot end fed is 1:1 on 40m, 1:1.2 on 20m and no higher than 1:1.3 on any of the higher bands through to 6m. I wrapped the toroid with even spacing on both sides, the way it was designed to be. As a CB antenna only, what you have is OK, the SWR is only costing you fractions of a dB, NOTHING anyone could hear on any channel.
