New antenna wiring
I have my antenna on a 35 foot mast above my house right now with the coax going into my room into a converter box total run is about 30 feet long with no preamp and I get about 38-34 channels regularly with no rotor.
My parents have decided they want to cut their sattelite and go back to antenna which we had up until 2007/2005 The want me to run it along the existing dish network wiring that is already in place and wired up to all the rooms (I know I will have to replace all of the splitters and stuff) there are three rooms each about thirty feet from the splitter and a 30 foot run of rg6 to the 3 way splitter. My problem is is that with the antenna hooded up to the existing coax with all the sattelite splitters removed I only get about 20 channels on the closest TV and 15 on the farthest do I need a distribution amp or a pre amp? Witch ever it is it would need to be able to be mounted outside (not the power supply of course) thanks |

If you were having trouble at your first 30 foot point, then an on-mast preamp would be a must. Since you are not seeing trouble with only one receiver at the entry point, it appears you can use a distribution amp at the first inside point to make up for splitter loss, and no outside amp would be needed.

OK thank you! Are the distribution amps that have 3 ports on them the same as the ones that just have one except the ones with multiple outs have an internal splitter?

Most likely yes. The only reason to have separate amps for each output would be to reduce distortion in a high level amp, which will not be the case here.
Warning - some of the cheap amps are not very good, tend to provide more gain than needed (on the theory that people will think more is better), and can have a tendency to oscillate. I had a RadioShack one that would oscillate, and the frequency would tune through the UHF band as you adjusted the gain. You could see this on analog TV as a herringbone pattern in the picture, but on digital, it would be hard to tell why you might be clobbering a particular channel's signal. I'm not prepared to recommend a particular brand - our expert is out at CES, so I can't ask him right now. |

The only reason i am asking is because I would like to place the amp a few feet ahead of the splitter.
BTW I would love to be at CES |

So you are looking for a single-output amp and external splitters - noted.

I had trouble getting digital TV to several outlets in my house when cable switched over. I bought little Motorola amps from Amazon and am very happy with them. They have amps with single outlets up to about four outlets.
