I need some authoritative advice for an outside antenna:
– Don't want to mess with an antenna rotor, so looking at omni-directional, hoping that the height of my roof (I'm on high ground, to boot) will at least partially make up for the loss of gain with a directional antenna. (The farthest UHF DTV station is 45 miles away, on a mountain, but I can not
receive it at all
with my rabbit ears; all the other stations come in like gangbusters.)
– I keep seeing antennas in my web research that are called "multi-directional."
I gather that these aren't the same as omni-directional, but rather have separate sections of the antenna that can be twisted in two or three directions, no? If so, that would seem not to cut it, for I have too many stations in random directions, which makes me think I need omni-directional.
– I know that a pre-amp can't increase the true gain of an antenna, but rather only permits hooking several TVs to the same antenna without loss of signal strength. In the analog days, it was best for signal/noise ratio considerations to put a pre-amp on the antenna
so it wouldn't amplify noise picked-up down the cable along with the signal. So my question is, with digital TV's pronounced higher threshold before noise becomes a problem (I understand that it's abrupt when it does, not increasingly more "snow" as with analog), does it still make much of a difference whether I put the pre-amp on the antenna, or will I be just fine with it inside the house?
– If omni-directional is indeed the way I can go, I'm looking at this
, which is available both with and without an on-antenna pre-amp.
What do you think?
