Currently using a RCA Pre-amp TVPRAMP1R

http://www.walmart.com/ip/RCA-Antenna-Pre-Amplifier/14554631

Have good success, yet some channels drop at odd times - crystal clear sky with no wind and work fine in a snow or rain storm...

Is there a better one to use? more power?

Thanks! Have learned so much just reading threads on here!

My personal experience with the RCA amp has been quite good. The amplifier tolerates strong signal levels better than many other amplifiers on the market.

The Antennas Direct 'Juice' would be on of the few alternatives I would consider...

Before spending money on another amplifier though, please consider posting a link to your TVFool reception prediction.

Also, what antenna(s) are you using and how high is the installation. Are there trees or other obstruction in the path toward the stations that you're having problems with?

I see you have a previous thread:
Around or over the mountains in Colorado
http://forum.tvfool.com/showthread.php?t=15872

Is this report still good?

You seem to be having the same problems as before.

I think it is going to take more than a new preamp to improve your reception.

What is your antenna setup now?
some channels drop at odd times Which ones?

I am repeating this post from your previous thread for background INFO.In Evergreen, Colorado - have one hill between my house and the Denver Lookout Mountain towers where the channels I want are located. Channels 2, 4, 7 and 9, 31 - the major networks. Tower is 11.1 miles per the report.

TvFool report - http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3db97dfcf930a984

If I point straight at the tower, I do pickup channel 2.1 ok, PBS 12 off the back and nothing else.

50' of coax to a Viewtv box - http://www.amazon.com/gp/product/B00GGVPKKC?

Just wondering if I have any hope of getting Denver locals with this setup? Networks from Cheyenne are fine, but miss the local news/weather.

And this post also; nice photos.

Trying a different antenna, added to a new mast above the other.

Dual Quad Bay Outdoor HDTV/DTV/UHF Bowtie
http://www.amazon.com/gp/product/B00DHHMOUW

Seems to have less drop outs on the channel 2, but still no other Denver locals.
Didn't play with it too much yet, still snow on the shady side...

Should I put a combiner up there and hook them together?

Here's a pic of my view to the tower

And the antennas

The terrain between the local transmitters and your location is very difficult for the signals.

If you click on a callsign in your report you can see the terrain profile. The transmitter is on the left and your location is on the right.

the channels I want: Channels 2, 4, 7 and 9, 31 - the major networks
2, KWGN CW, virtual channel 2.1, real channel 34. NM 6.1 dB

Here is the terrain profile using different software:

The signal coverage is very spotty because of the rough terrain:

Notice that only 58 of 1000 kW ERP is sent in your direction because of the transmitting antenna pattern

I doubt that another preamp will improve your reception, unless the RCA preamp is defective.

You might be able to improve the reception of 7 and 9 if you replace the RCA antenna with an MCM 30-2476

If your Dual Quad Bay Outdoor HDTV/DTV/UHF Bowtie isn't able to receive the local UHF channels with both panels aimed in the same direction, I doubt that any other UHF antenna will. A longshot replacement would be an Antennas Direct 91XG because it has a tilt adjustment that would allow you to tilt the front end up to better catch the signals as they come over the ridge.

An extreme solution would be a pair of 91XGs side-by-side:

DON'T FORGET ABOUT 18Gage solid copper RG 6, not cc,steal when you use mast mount amplifiers like the R C A at30:DB gain,

Thanks for the replies! Guess I need to pay more attention to the forum...

I swapped the positions of the VHF and UHF antennas on the mast (which I replaced with a
longer 1 1/2" conduit pipe) - now I get a CBS, NBC and CW - from Cheyenne WY of all places!
5-1 KGWN-HD http://www.kgwn.tv/ CBS Cheyenne
5-2 KGWN-NC '' NBC Cheyenne
5-3 OGWN-DT '' CW Cheyenne

Silly mountains. Next up is trimming some tree tops with the 12 gauge. While checking out that other antenna, http://www.mcmelectronics.com/product/STELLAR-LABS-30-2476-/30-2476
