Actually,,, With Channel Master's top end antennas that is not, entierly
, true.
You see, the top end antennas have a compartment at the head (antenna)
end, this compartment contains either the proper matching balun (300 or
75 ohm) or a pre-ampolifier (and CM's pre-amps are very good, at least
in my expierence, which I'll admit is some decades old)
So, if you are willing to climb up the tower (I was, even if I do suffer
from acrophobia, let me tell you, 100 feet up, even with a safety belt,
was not exactly fun) to pop in the head end unit, you can put the
antenna up, make sure you put a junction or other device where you are
going to put the power adapter (In my case in the basement), next to the
power mains) you can always after-instalation climb up and make the
change.
now... Where I'm at now (Detroit) I'm only a few miles from most of the
major television transmitters... If I put a pre-amp in I have to be very
careful to avoid front end overload (That is, I can use one, but only if
there is a distrubution block downstream, at least a 4-way splitter or
don't use a pre-amp)
Thus, I have 2 antennas on this house, both split two ways
