[Antennas] gamma match

Wed Jan 12 05:08:49 EST 2005

I am attempting to adjust a gamma match on a new home brew yagi antenna 
for 10 metres. I have a variable capacitor which appears to adjust the 
reactance to approx zero on my home brew noise bridge, however the 
impedance appears to be about 18 ohms and it doesnt seem to matter what 
I do it appears not to change. I am obviously missing something (apart 
from not knowing enough about what I am doing). Any suggestions please 
as to what to look at??
