Hey guys & gals,
I received this DTV antenna question from a friend who's having problems
with her setup.
My only thinking is that the amplifier has raised the "noise floor" all
around, and now that's she's higher, she's more directional.
I'm recommending removing the amplifier.
What do you think ?

I am having a problem with my antenna and TV setups here.
As mentioned before, I have been running off an antenna hanging inside the
garage just over the roof of the Mercedes.
I live not quite in a direct line between Chicago and Milwaukee.
Heading of 172 degrees and 57 miles to Chicago, and 358 degrees and
about 30 miles to Milwaukee. The antenna was pointing (roughly) at
Chicago, I got most of the Chicago stations very well, most of the
time. (CBS is always bad). And most of the time, I also got Milwaukee
just fine. Once in a while, with bad weather, one city's stations or
the other would not come in as well. But some of these are duplicate's
(like 2 ABC stations etc.), so on the whole it worked well.
Well about a month ago, I decided to "improve the situation". I moved
the antenna up to the roof, so it has an increased height of about 20 or
more. I also installed a rotator and an amplifier. The cable run is no
longer, but because of the amplifier, there are two more carefully
checked connections. I wanted to do this before the permanent winter
accumulation of snow had deposited itself on the roof. It is now snowed
Now when I point the antenna at Chicago, I get the Chicago stations very
well, even better than before. BUT, I cannot receive the Milwaukee
stations at all. And the same for the other directions. Point it at
Milwaukee, cannot see the Chicago stations. So you ask, what's the problem?
In order to watch ANY station on either of the TVs, you have to do a
channel scan. You CANNOT add a station that is not found by the TV in
its automatic scan. You can subtract a channel, but not add one. You
cannot even punch the the numbers (like 04.1) for a channel that was not
found and loaded into the menu by the automatic scan.
SO, if I point the antenna at Chicago and do the scan, I can only watch
those stations until I rotate the antenna and rerun the automatic scan
(a process that can take 10-15 minutes) if I want to watch a Milwaukee
station. And the stations are not all duplicates, and I really want the
ability to receive both.
It is so frustrating !!!!
And I don't get why the "bi-directional" reception has degraded so much,
when the individual channels (in the specific direction) seem to have
I know that there are many experts on everything on this list .........
