I hate adjusting gamma matches through trial and error. I am hoping my new
antenna analyzer will help.
I computer designed a 10 meter Yagi which designed at a feed impedance of 31.2
+ j18.3. This is inductive, I assume.
I have a gamma match, the antenna mounted at 15 feet and my antenna analyzer
says (through an analyzer measured 1 wavelength 50 ohm feed line) Z=66 ohms,
X=-52 ohms and C=105
My take is to move the tap closer to the boom until it is about Z=50 ohms and,
if there is still a negative X, to lengthen the DE. Of course, the changes
will interact with each other and I will need to go back and forth until Z=50
and X=0.
Am I on the right track?
