Hello, All:

I've been thinking about ways to improve my signal on 80 meters from my .3 acre 
suburban lot.? Have a SteppIR yagi with the 40/30 kit so those bands are well 
covered.? ? I'm contemplating using my existing 43 foot vertical as the 
vertical portion of an inverted L for 80 meters, and then running a wire over 
to my tower for the horizontal component.?There is already a passable radial 
system under the 43 footer.? The inspiration for this came from the ON4UN 
chapter on Inverted L antennas, where there is a diagram of such an antenna 
using a 1.6 inch diameter 39 foot vertical pole and a 40 foot 12 AWG horizontal 
wire.? Has anyone done anything similar using?one of the commercially available 
43 foot vertical models?? I don't have?experience with modeling software, and 
am wondering how long the wire should be for resonance around 3.600 MHz.? What 
would be the best method to feed it?? Any and all comments welcome.? 73 de
.?
