Corrected responseYes, you can reverse the splitter to make it combine the two signals
and keep the proper impedance. The only problem is.........the two
antennas may be located far enough apart that the signal induced
into antenna A may be out of phase with the signal induced into
antenna B. When this happens with an analog signal you may
get ghosting or just a reduced signal level that would not justify
using two antennas. With a DTV you may get a inferior signal level.
To reduce the possibility of out of phase antennas you should try to
mount them side by side so that the distance to the transmitting tower
is the same for both. On the upper frequencies a half wave or 100%)
phase shift is only 8 inches. On the lower frequencies it is around
2.5 feet. Keeping the antennas perpendicular

(to the transmitter)

and side by side is your
best bet. Signal deflection from mounting the antennas inside could
also cause a out of phase problem. Good luck.

But the OPs problem is (and this is probably common) he wants to pull
in signals from different transmitters at different compass points.
He wants one antenna 'pointed' at one transmitter, and another antenna
'pointed' at another transmitter. *If you can't combine two separate
antennas in this way without their interfering with one another, maybe
a rotor really is the only way to do it. *-- H- Hide quoted text -

I've had good luck with attic antennas.

But the tv wants to "see" one particular impedance, 50 or 75 ohms (I
no longer remember. It may even have changed.)

Amateur radio types use antenna matching networks (tuners) to make
sure the equipment matches the antenna impedance. You might need one
of those.

Easiest of course is an A/B switch. That's what I'd do. Though it
won't work with your remote.
