In my last post I explained the need for and thought process behind my antenna construction project. In this post I’m going to talk about actually building the antenna.
I had settled on a vertical dipole design that closely resembles the venerable NorCal Doublet. The NorCal Doublet is 44 feet long with a 28 foot feed line. It’s usually fashioned for portability and backpack-ability, and is typically deployed horizontally like a dipole.
My antenna will be a permanent base antenna and will be mounted vertically. I’m quite tempted to call it the “AH6TD Vertical Doublet.” Again, I digress…
Anyway, I’m building this antenna to be more permanent and, since . . .

Here at AH6TD we’ve been running a vertical dipole for well over a year and were very happy with it. However, it would only tune up on 20 meters and higher, and I would really like to use it on 30 and 40 meters as well.
So I started to consider what my options might be, and wound up composing the following list of design objectives for a new antenna to replace my venerable vertical dipole:
Must be built using parts I already have — no out of pocket expenses. Must be no less visually appealing than the existing vertical dipole in use (in the XYL’s judgment). Must be . . .

Wondering why elevated vertical wilth 4 elevated radials, all at quarter-wave resonant lengths on 40m has 99:1 swr in CocoaNEC. Only 40m…
I managed to work Japan and New Caledonia last night around 5:30 Zulu, 14.070. Not the best conditions. Maybe it’ll be better today!
