[Elecraft] Best way to secure RF ground from 2nd floor?

[Jim Miller]

i believe the originator had said that he has a centerfed dipole with a 
balanced feedline.

i think the first thing the lead wire should come to is a suitable matching 
device. i use an elecraft t1 which works well for my qrp activities. the 
coaxial input to my t1 has 10 inches of suitable ferrites on it to act as a 
common mode rf choke to keep rf off the exterior of the coax regardless of 
it's length.

that ensures that whether the feedline is perfectly balanced or not all of 
the rf is properly contained inside the coax. the tuner itself is likely a 
bit hot but it is of no consequence.

my next oft delayed project is to build up a simple insertion/extraction 
pair for a bit of dc onto the coax to remotely trigger the t1 tuning cycle.
