[50mhz] Yagis: an economical solution that doesn't involve alot of work.

Tue Aug 24 01:13:15 EDT 2010

Carl,
Not exactly...I was proposing a simple coax core and aluminum tube type of
gamma match, not what CC did on HF...I'm thinking this is a decent
compromise between the bogus ceramic gamma match and the T match.

Thanks & 73,

Which is what CC did on their HF monobanders for decades. Personally I 
prefer an all metal T Match for 6M, no loss, better balance, higher input 
impedance, better bandwith with efficiency. CC used a T on the 6M Boomer.
