Two more points:

1) TVFool and the like are generic, and may not apply to your exact situation. They do not carefully use USFS relief maps to know how shaded you might be by the edge of a mountain, so assume their conclusions to be a guess on the high side.

2) a "30 mile" antenna does not, sadly, mean good reception up to 30 miles. It probably means "under the best possible conditions through the vacuum of space with no obstructions or reflections", meaning in the real world it might work OK at ~2/3rds of its rated distance, and then maybe not consistently.

You can not have too much directionality where you are. Use the most-directional antenna you can get.

There's no place like 127.0.0.1

Every reception site is a bit of a crap shoot, and to stay in business "Mr. Antenna" should try to bear down a little bit, and not leave until you have a working system, IMHO.

Maybe its not "Mr. Antennae", because that is the only single antenna he had? Maybe he was too lazy to climb up the ladder again and swap it with a better one? Maybe there was an agreed on price and a little better antenna would cut into his profits?

You need a better (read: more directional) antenna, such as a Channel Master 4228 HD. While not spec'ed for high VHF, they do pretty good. Your problem with 8.x may be because the antenna up there is not capable of both UHF and high VHF.

My guess is that you are getting some edge glow spatter around the Mt crests, which is a form of multipath interference. A more directional antenna should be able to find a beam without as much interference. Oddly, sometimes you have to point an antenna somewhat off axis to get the best reception in a multipath environment. Sometimes you have to move the antenna 5 or 10 feet to get out of an interference node. You likely do not need an antenna preamp under 50 miles away, and the preamp will just amplify signal and interference equally (plus add noise), meaning that at best the RATIO of signal to interference will not be improved, and that is the key thing that a directional antenna can do. You likely would not need a distribution line amp unless you are feeding a lot of sets over distance.

But "Mr. Antenna" should know all of that, and should have provided you with a more reliable system by employing a better antenna and better positioning/aiming technique. I hate to be cynical, but it sounds like you got the bare minimum treatment needed for him to get paid. Try your best to not let them off the hook, because it seems like you did not get delivery on what you probably paid for.

If you paid with a credit card it may be possible to contest this.
I agree with TomCat on Mr. Antenna, in all respects. Get them back out.
