[TowerTalk] Dumb question on Mosley TA33

[Dan Hearn]

Tom: The use of a coil of coax as a choke is a poor solution to the problem
of feed line radiation. It is affected by the feed line length and distance
to ground. Not only that, it is not well suited to use over the 3 bands of
your antenna.  Modern technology using ferrite cores allows you to generate
thousands of ohms of impedance over a wide frequency range. Design of these
chokes is covered on K9YC's web site. They are simple and inexpensive to
build or you can buy them from Balun Designs or Array Solutions for way
under a hundred bucks complete in weather tite cases. . The cores are made
by Fair Rite and can be bought from Mouser or other parts houses.
