Thanks Pete and Sinisa...

I was just trying to get an idea if my QRP operation would be better 
suited to 1/2, 2/2 or 3/2 length endfed antenna with the wire directly 
tied to the center conductor out of the rig and a suitable (if 
necessary) counterpoise wire - thereby eliminating all feedline.

I have a big pile of wire and was wondering, before I go chopping it up, 
if anyone had tried connecting the antenna wire directly to the SO239 or 
BNC connector with no feedline and had any recommendations as to which 
performed better, the 1/2, 2/2 or 3/2, or even 5/8, etc. for a given 
band or set of bands.


I had read here and there where a vertical endfed antenna seemed to 
outperform a generic dipole under the same conditions, height, etc.
