[Amps] Ten-Tec Titan 10 Meter Input SWR

[TexasRF at aol.com]

Like Bill said, changing the coax length does not change the swr so there  
is very little "tuning" going on.
 
Using 1/4 wave or less will not fix the swr problem so something more is  
needed.
 
Changing from 50 to 75 ohm coax will cause some tuning to take place. Good  
luck finding a happy length though.

If you  change the length of the feed coax, you have created a "coax tuner".
1/4  wave or less is all that is required.
