[TowerTalk] 4 square for 80

[Tim Duffy]

Hello Jim,

We are talking about feedlines that are 20 feet (feedlines) above the
ground. They have to be choked (both ends). The raised radial application
(which is not as good as the ground mounted solution with 64 plus radials).
The feedlines must not be radials - that is why they must be choked.

73,
Tim K3LR

The radials are not connected to anything at the far end. The feedline is.

I've seen several recommendations from people I view as "authorities" 
say that the feedlines of vertical antennas should be choked. Sorry, I 
don't recall who.
