Antenna question

Archived from groups: alt.tv.tech.hdtv (More info?)

I just asked a question about a preamplifier on the antenna a couple of days
back. You may want to read it......

Anyway, I have a 100 mile VHF, 60 mile UHF antenna. I really can't get much
with thg antennaa unless I add an amplifier at the TV. But even the
amplifier at the TV is not enough and some channels drop in and out, so my
next step is to get a preamplifier that is put near the antenna to boost the
signal strength. Based on the responses to my question on this newsgroup, I
found this page when searching for a CM-7777 preamp whihc has a lot of
interesting information about antennas.

Yes. Most if not all digital signals are on UHF and an UHF only
antenna works better than one for both VHF and UHF because there is no
compromise.

Radio Shack has a UHF (U-75) that will out do the UHF from VU 190 and it
cost less than $25

A Good baseline UHF antenna covers UHF Channels 14 thru

59 Very Well and VHF Channels 7 thru 13 OK..... Bad on 2 thru 6..

A Channel Master 3021 4 bay bow tie goes up to

60 miles in rural areas..... 40 miles very well in

Medium sized cities.... and Costs $25....

It has a rather wide aiming pattern which is OK too.

For pure UHF reception Power... a $52 CM 8 bay bow tie is

'King'.....

Please use RG-6 antenna cable for HDTV.....
