[TowerTalk] [Tower Talk] Current Baluns for 4SQ verticals

On all of my HF antennas at the W5KFT-Ranch station I am using
Amidon FB-43-1020 beads at the feed points.  These are round and
about 1.5 inches long.  They are big enough that they slide over 
the outside of RG-213.  In this way I dont have to mess with
any extra connections between the choke and the feedpoint.

I just put them right at the feed point on the pigtail that 
feeds the antenna.
