HI Floyd That is what the one I designed this one after looked like. I was just wondering if the cut off wire made any difference in the operation of the antenna. Thanks and 73 Tom W7WHY ____________

That is what I do here. Using an old Johnson Matchbox and the antenna works like gangbusters on ALL bands. 73 Tom W7WHY _______________________________________________ ______________________________

Hi Al What I have done is mount the beam so that the reflector is close to the ground and pointing upwards if possible. Can get pretty good readings that way. 73 Tom W7WHY ___________________________

I had some of that 450 ohm ladder line with copperweld wire and that stuff was terrible. It rusted like crazy where it hooked to the antenna. After about 6 months I had to lower the antenna, cut the

No -don't remember. One of the locals got a 1000 foot spool of it and I bought 100 feet from him. That copperweld was really stiff, too. I will never buy ladder line with a solid conductor again. 73

Hi All Today I put together an EFHW antenna for 40-10. In checking it out, the SWR was good and all looked like it was going to work. Made one contact with it, running around 500 watts, and the core

I put up an EFHW and it worked. I just don't know how we ever put up antennas back in 'the day' before modeling. I worked 260 countries with a Gotham quad tribander. You know - the one with aluminum

Why would anyone pay $1000 for a 28 foot piece of aluminum? This seems like as big of a rip off as the 43' vertical for $700. 73 Tom W7WHY _______________________________________________ ____________

Problem with copperweld is rust. When you scratch the copper away it makes a rusty mess. I had terrible problems with copperweld twin lead rusting where it connected to the antenna. 73 Tom W7WHY ____
