Topic: Antenna Preamp Q Posted: 13 Sep 2021 at 7:58pm |
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? |

Might not be related but some channels changed frequency this year so if you haven't done a rescan in awhile you might want to try that.

+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? |

Which antenna did you switch to and how did the install go? Can you quantify the improvement? Does it rotate? |

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.

You're right, it doesn't make sense. Thats why I posted the question. As far as I can tell, my antenna doesn't rotate. It is on a pipe that penetrates the roof and has 2 blades extending from a round body. The blades are orientated parallel to the long axis of the trailer. I've always thought it was OEM.

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.
