[Antennas] coil to match 80 and inverted L

Mon, 14 Oct 2002 16:42:17 -0400

Bill;

If the Inverted L is 1/4 wave, it should match directly to 50 ohm coax. 
IF it is 3/8 wave, then only a series cap is needed to tune out the
reactance.
I have had both and prefer the 3/8 wave versions. (351/f(MHz & 200-300 pF
in series)

Good luck....73,
Jim, K4SQR
