I've never understood the value of a feedpoint choke for a typical

It prevents the feedline from becoming part of the radial
system/counterpoise, and thus part of the antenna. Without a choke,
there is the potential for RF in the shack, and for noise coupling from
the shack to the antenna. I have no serious observations about either in
the field, but I do use a choke at the feedpoint of my three 160M
verticals. If you roll your own, the cost is modest.
