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.
