I just got 2 antennas professionally installed by a firm that has been recommended by this forum,,One antenna is turned towards NH to pick up WBIN and NHPrine and the other is turned towards the Boston antennas. The installer swore that all that was needed was to connect the signals from the two antennae into a splicer (turned backwards) and then amplify. I'm finding that many channels are completely unwatchable; I think we're going to have to somehow return to cable in order to watch the game tonight. Channel 5, WCVB, with it's high power, is the only channel that is reliable. This morning, I was unable to watch meet the press on ch 7 and fox news sunday on 25.1. I've had problems, really, with all of the other channels, but perhaps a couple of the PBS stations are a bit better than some of the others From FCC information, I believe this has something to do with the power of the station, but I am not entirely sure about this diagnosis yet. My symptoms are:
* (least often) I can get pixellation with sound that is ok,
* I can see a talking head but have no sound,
* I get freezes.
* I get freezes with an annoying buzzing-flutter sound.
One of the above interruptions happen once per sentence and it is totally unbearable.
I live close to the Boston transmitter, TV Fool and the other online tools say that I should be able to get all of the channels (contact me and I'll give you a link) but TVFool may not be appreciating that I live in a bit of a valley and there are buildings, trees, and hills in the way.
My question is :
* How can I tell if the problem is interference between the two antennae? Or is that even a potential problem?
* How can I tell how much power that I have on each channel and whether it will ever come in? Is the only way to do this with the installer? Shouldn't the original installer have somehow ensured this?
* Is there anything I can do to improve my signal? Filtering? Amplification?
* If the problem is one of adequate reception, is there anything thatt
Merging two antennas, aimed in different directions, together into one downlead will result in reception blackouts when signals from the wrong direction interfere with signals from the desired direction.
Professional antenna installers should be aware of this known problem, common to areas between major cities.
There was an antenna installer who made a lot of money for himself combining antennas aimed at Chicago and South Bend that suffered the predictable result. He also made a lot of money for the cable company as viewers abandoned their new, expensive, professionaly installed outdoor antenas blaming "digital television stations" for their reception problems.
As proof, you will discover that disconnecting the "wrong" antenna will definitely improve reception from "deisred" direction.
As suggested, two downleads from two different antennas to an A/B switch at the back of your TV receiver allows selecting the desired city without blackouts from the wrong direction. You may have to use two parallel distribution systems to several switches if you have multiple TV receivers.
A more extreme solution would be purchasing multiple single-channel DTV processors for each station from one direction and injecting them into the antenna system from the other direction for switchless single cable distribution.
