Which end of roof tv antenna toward station

Posted by Jimw on May 1, 2009, 10:26 pm

I bought a used rooftop tv antenna at a garage sale so there are no
instructions. I know how to mount it and connect the coax, but I do
not recall which end points toward the tv station transmitter.

I know the UHF elements are the smaller ones and the VHF are the
larger ones. But which end goes toward the station? Here is a crude
drawing (below).

You'd think there would be a diagram on the web, but I sure can not
find one. They should mark it right on the antenna but they dont.

Get yourself a "low noise amplifier" for the mast of the antenna.
It will really improve your reception. Radio Shack has some.

The longest elements are always the back side of the antenna.

Hi,
Basically, there are multi element on a boom. Shorter element side
should point to the station. Short element is called director, longer
one is called reflector. The more elements, the more gain.
