[TowerTalk] Full wave loop on 80m : Impedance 50 or 75 Ohms??

[n4kg@juno.com (n4kg@juno.com)]

A simple way to match 100 ohm antennas such as
full wave loops or resonant long wires fed at a current
maximum is to use a 1/4 WL 75 ohm coaxial transformer.

The formula for 1/4 WL matching sections is 

Rin X Rout = Zo squared  
where Zo is the characteristic impedance of the matching sectiion.
