Just to add a comment on this thread: I do not use an inductor to match my inverted 'L', just a capacitor from coax centre/bottom of wire to the radial point. Further I do not use big wide space 'toa

The excellent web site for calculating matching network values should have been: http://home.sandiego.edu/~ekim/e194rfs01/jwmatcher/matcher2.html not the one I posted yesterday. 73, Tom G3OLB _______

Just measured the 'hairpin' coil for my 160m 38 foot top loaded - coil and 2 x 18 foot wires - antenna. Feedpoint impedance without match is 12 ohms. Placing shunt coil to ground of 1.7microH and tx

I modeled my "Marconi T" antenna using EZNEC, got complex impedance parameters at feedpoint, plugged these into the L-network calculator that Tom mentions to find an L-network design, made an air-wou

Yes, EZNEC does work!! I've had great success with it over the years. It was great for my home-brew (home-EZNEC-designed) single-feedline 5-band quad. It was great when I was building and tuning it t
