Antenna Preamp Q

Ah yes, the old bat-wing antenna. I had that on our 2016 RPod. After replacing it with another of the same type and having that break also, I replaced it with a flying saucer that doesn't have the wings. It is a little larger in diameter and seems to work just as well as the bat-wing antenna if not better. However, the last time I looked, the brand I purchased did not seem to be available (ordered from Amazon). If you do order a replacement, try to get one with the same mount type so you can just re-use the existing mount and not have to change it.

Is your antenna the kind you can rotate?  On mine I go into the TV set up and it has a signal strength meter and I set it on the channel I am having an issue with and then rotate it to see if I can get better signal strength.  Doesn't make sense that a preamp would work with other channels and not a single channel but that channels antenna could be in a different direction than your other channels.  If the preamp is picking up an extremely weak signal it may not work.  Just a guess.

Originally posted by GlueGuy +1 to what OG mentions. The FCC is continuously auctioning off old frequencies and assigning new frequencies. It's likely that channel 45 (in your example) has been assigned a new less optimal frequency. If it's like the TV stations around here, they may need to get a different transmit antenna or change their power output or some combination.

LOL. How would rescanning help me receive a station I get with the preamp off but not on?

Ive researched this problem and find a lot of people including myself have problems with factory antenna.  alot of people change it to a new one. 

I have a curious situation with my antenna preamp. Most channels come in better with it on, but channel 45 won't and the signal is weak/broken with it off. TV says "no signal" with it on for ch 45.

What could it be? Preamp going bad?
