Looks good, but I'm willing to bet it won't work as well as your Sigma 4 clone. I had an Astro Plane before I got the Sigma 4, and the AP performed worse than a standard 5/8 wave GP. The Sigma 4 was about 1 S-unit stronger than the 5/8th wave.
I miss HomerBB. He always had an interesting antenna project going on. I wonder what happened to him?
Bringing yesterday's CB radio fun into the 21st century.
If you're in the SE-PA area, join us Wednesday nights on Ch 13 for "Classic Radio Roundup", where you can hear a bunch of yesterday's radios strut their stuff in fine style.
So I saw the aluminum tape post and thought I'd try it. I changed it up after I realized I had gotten in a twist and glued my fittings wrong so I figured I'd keep going. It works nicely anyway. It's a little shorter than the real one in height, but it gets good reports. Swr is not bad, 26.965 is a 1.7 and it goes down the higher you go. It was lower on the ground before I put it up. It needs to be higher over the roof than where it is, but I ran out of mast. I'll post a picture if I can find it. I'll build another one for fun and mix the original measurements and the one I goofed and see what happens. I'd love to get someone to model it in software to see what it says.
