Finally built my SBGH!
After many fits and false starts, math errors and skill shortcomings, I finally hobbled my version of the a single bay Gray Hooverman.
Here's a closeup of the feed-point
I tried using a cheapo Craftsman drill press adapter thing to drill holes through the 1" salvaged square aluminum tube to insert my reflector mounts through, but the thing just wasn't precise enough when I got into larger bits.
I ruined one tube, but since it was something I salvaged it wasn't so bad.
That did though sort of put the kibosh on building a DBGH.
I decided to recycle some parts that had held on larger hollow tubing to the old VHF antenna I was scavenging. But this also limited me to the SBGH because I only had enough cleat things to make a SBGH like this. (back view)
Since it's clear skies until Friday night I'm going to wait til tomorrow to ground it and all, but I'm enjoying the reception tonight. I can pick up few more distant channels, though there's nothing really within 100 miles that I can't get locally so it's sort of moot for range.
I do now though get all five bright green bars on my PBS station which is 40 miles away, so I've really been enjoying "Carrier" tonight on PBS.
Thanks to Autofils for this great design!
