Hi Chris,

 

I wouldn' worry&n= bsp;about that.

Assuming that&nbs= p;you aim at 50 Ohm = the SWR will&nb= sp;be 1.1/1.

This will ca= use a reflected powe= r of 0.2% (or otherwise: = a decrease of 0.01dB of the radiated power).

I now have my&n= bsp;loading coil run= ning without a matching transformer, as
I have very slightly improved my ground. I get a&n= bsp;Zmag of 45.6 Ohms, is
it worth worryi= ng about? Thanks, a scan is at:
