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.
