[TowerTalk] High power 2:1 transformer was Re: 16om vertical and the number of radials

[Pete Smith N4ZR <pete.n4zr@gmail.com>]

A somewhat related question - as the R component at the feedpoint of my 
inverted L goes down toward 25 ohms, I've begun wondering if I should do 
some matching at the feedpoint, rather than using my tuner in the shack, 
even though feedline losses at 160 are relatively low.  Can someone 
point me toward a good way to do a 2:1 downward transformation?  I 
already have a common mode choke at the feedpoint.
