I need to get a Pre-amp to pick up two channels clearer and eventually to pick up digital signals as well. What is the best pre-amp to get. My set up has an antenna in the attic which is picking up most channels 60 miles away, but two of the channels are a few degrees from the others. I have the antenna running through a coax that runs from the attic using a cable that is also being used to send a dish signal to the room next to the attic. It then goes out to two TV's. The coax runs are fairly long because they run from the attic down to the basement and back upstairs again.

What is the best Pre-amp to get?

How far away are your stations (any FM or TV repeaters within 5 miles)? What frequency ranges are you looking at UHF, VHF both?

Give us your zip code and we can give you a more informed opinion.

The second to last number is the number of miles from my house. My house sits up on a hill.

5, 19 and 50 are a little snowy, but watchable.
4 and 62 are pretty bad.
Rest are pretty clear.

You'd probably need to notch (filter) out the nearby stations before using any preamp....they are likely to even overload a tuner that's fed directly without a preamp.

You'll also likely need to trap out the FM band, too. You can check for AM, FM, and all types of TV stations within your area, via the "search" pages on the FCC website, www.fcc.gov.

This might be a job for a good local antenna installer....at least a consultation with one.

I was using a pre-amp on my antenna, then I decided to "upgrade" to improve the signal... all the new pre-amp did was overload the signal, and lower my receivers ability to tune in stations.

If you are getting your stations, then you probably don't need a pre-amp.

I am not getting all of the stations I want. Plus, when I get digital, I would like more than just 4-5 channels if possible.

How do I filter out nearby stations?

Any high output pre-amp will overload with stations as nearby as yours are.

I have a Winegard HDP-269 pre-amp. I is designed for urban use and is resistant to overload. I have a full power DTV station 2.5 miles from my house and have no overload problems with the 269.

Channel Master 7775. I used a professional installer to handle my initial install cause I live in an area that's just a killer when it comes to multipath. That was his recommendation.

Good luck.

I'm 9 miles from the towers in Albany. My HDP-269 overloads. The overload prevents reception of out of market digital signals.

If you can streamline the coax runs, perhaps use a better grade of cable and be sure the connectors are properly installed then the best preamp may turn out to be no preamp.
