Topband: Capacitor for Inverted L

[Gary Smith]

I used to use an ugly, beat up 500pf vac variable at the base of my 
160M inv-L & used the MFJ SWR Analyzer to adjust it. The CAT-5 cable 
I used for wire was brought up over a tall tree and chafing from the 
wind blown branches wore through it 1/2 times a year. After the 
antenna came down the last time I used a more rugged wire and cut it 
135' long and have it connected to a radial plate which serves as a 
common tie-in for my separate 160, 80, 40, 30 meter vertical wires 
but also my butternut HF9V which I use for 20 & up.

The 160M ant will not cover the whole band but as I rarely go above 
1.9 Mhz, it's perfect and needs no base loaded cap.

YMMV.
