Re: [TenTec] 160 M antenna

[Steve Hunt <steve@karinya.net>]

Rick,

The original article was in Radio Communication November 1986. The 
mechanical tuning mechanism was not for the faint-hearted :) but if you 
already have a spare screwdriver antenna it's a good option.
The same RSGB book that had Tim's article also had mine on a 40ft 160m 
vertical with capacity hat loading. I used 6 wires (part of the guys) 
with "perimeter" wires - they make a big difference to the capacity and 
don't introduce opposing current vectors. The article includes a plot of 
how the feedpoint resistance changed as I added radials.
Sketch of the antenna here:
