Transmitter RF getting into ethernet

Lionel

Inadvertently while rushing around, yes, and the RF into the shack lit the place up.  It was unpleasant.  That bump from a balanced feedline to coax seems like a big deal.  I have seen some say that you don't really need the choke but I think unlikely to work well. 

By the way I am using a current choke 1:1.  I've never tried 4:1 but suspect the result would be a low impedance at the tuner, on some bands, that would be out of range. 

$50 isn't a bad price from that company. 

Good luck with your installation.
