I recall helping put up a beam for the Denver Radio Club station in
about 1972 or 3, and one of the instructions was to wind the coax into a
choke at the feedpoint. At the time I didn't understand quite why or
what it did, but it was there in the instructions. Don't recall what
kind of beam it was, but considering the popularity of the TA33, it
might well have been that model.

That your TA-33 manual calls for a 5-turn 6" diameter balun fabbed
from coax is welcome news, Bill, Mr. Mosely must have gotten religion
lately. I had a 33 when they were first made available, but no balun
was included. So I had a talk with Mr. Mosely (I've forgotten his
first name) and asked him why no balun. He became irate when I
admonished him for excluding the balun. He said his antennas were
designed to not need a balun, and he admonished me for claiming they
needed a balun to avoid pattern distortion due to unwanted radiation
from the feedline. He kept that same erroneous viewpoint for as long
as I know, until your manual now calls for a balun. Will wonders never
cease!
