An A/B switch seems like the best bet. This assumes the antenna is 75 Ohms;
if not, you need a 300:75 Ohm transformer. I assume the sat receiver input
is also 75 Ohms. If you connect 300 Ohm twinlead to it, it won't work well.
How do you connect to the TV - F connector, or screw terminals? See if the
TV has 2 antenna inputs. A lot of newer TVs do. That would let you switch
sources using your regular remote control

Can I ask a tv antenna question here?

My satellite service does not include local channels. I have an indoor
antenna that if connected through the satellite receiver gives me very
poor
reception. (Why?) If I connect the antenna directly to the TV, and not
through the receiver, the reception improves dramatically. However, this
requires having to manually connect and disconnect cables all the time.

Can you help?

Thanks.

This is way over my head. Can you walk me through this?

How do I know if the antenna is 75 Ohms? What is a 300:75 Ohm transformer?

Thanks.

TV coaxial line is 75 ohms. TV twinlead is 300 ohms. 300 ohms is the
older standard for TVs that once had two antenna screw terminals.
