Default TV antenna-rotor?

Yes you can combine the antennas with a splitter.
That is why they are called splitter/combiners.
The bad news is that you get almost one half the
energy out of a splitter/combiner that you put in.
There is a nearly 3db (50%) insertion loss. If


I'm used combiners with TV antennas in a stacked array. Two antennas
(on TV) is far better than one. Now if there was a 3 db loss in a
combiner, I would gain nothing as stacking gives about 3 db gain (on a
good day, down hill, and with a tail wind)

you had two antennas, each pointed in a different
direction you might solve your problem. The rotor
is probably the most aestically pleasing solution,


It can be a bit of a problem if your antennas are below the top of the
tower, but I used an arm with the rotor mounted out from the side of
the tower by about three feet and get 240 degrees of rotation. It
just so happens all available TV stations are within that 240 degree
arc.

Roger,

He is talking about having the two antennas pointed in different directions.
Bad news for ghosts.

Ghosts live in the land of strong signals and good
multipath. Several persons in my area of the
world (the southern portion of the northern state
of Delaware - the two smallest states in the
Union) will point an antenna at Philly and another
at Baltimore. They are not troubled by ghosts.
Ghosts result from two, or more, signals reaching
the receiver close enough together and in
sufficient strength to become part of the picture.

And here I thought ghosts thrived in that

situation.:-))
