[Elecraft] RFI and Direct tv or Dish network

[Warren Merkel]

Thanks for the note Jim,

However I've already got multiple passes of the OCF Feedline fed through
a stack of five 2.4"  #31 donuts, per your very own, excellent
RFI-Ham.pdf article.   Picture on my QRZ page.

The RG6  has a stack of three donuts with a large number (didn't count)
of turns, located at the demark point to the house.  I guess I could add
another set and spread out the Z over frequency a bit more.

I believe I need to look for other entry points to the entertainment
system as a whole, as the DirecTV DVR is network connected and of
course, connected to an AV receiver.  Lots of points of entry to squelch.

Warren, KD4Z

Your antenna, an off-center-fed Windom, is notorious for generating

common mode current on the feedline, and there's no way to choke it 
effectively to kill that current. So what you're calling a feedline 
Mother Nature calls part of the antenna. THAT'S a primary cause of your 
problem.

If you're having issues on 80M, you'll need at least 13 turns of the RG6 
through a single #31 toroid to make a dent in the common mode current.
