[Hallicrafters] Re: Dipole antenna

[Glen Zook]

In theory, yes.  In a practical situation, probably
not.  Amateurs have been feeding dipoles directly with
coax for decades.  Sometimes adding a balun might help
slightly in the pattern of the antenna.  However,
there are so many objects near most dipoles that
distort the pattern that in most cases you would have
difficulty measuring the difference let alone noticing
any difference in performance.

There have been amateurs who actually noticed a
decrease in performance by adding a balun.  But, in
general, adding a balun will have little, if any,
effect on the performance.  There are exceptions, of
course, but I wouldn't go out and purchase a balun to
put on a dipole type of antenna.

I have a question: My high (75 feet up)  40 meter
dipole antenna is connected directly to  a coax (per
ARRL handbook) instead of having a balun between the 
antenna and coax.  I could build (or buy) a 1:1 balun
but am I likely to see any difference?
