HD Dropouts

My local CBS station recently upgraded their power from 400kw to
1,000kw. Since the upgrade I experience frequent dropouts that appear to
be multipath interference. Before the upgrade my reception was fine. The
signal bounces off of a repeater that is within 25 miles of my house. I
can see the lights on the tower at night, so I have a clear path to the
signal. I have a 100" Channel Master antenna that I bought when all of
the local HD signals were lower power (some still are low power). Is my
antenna too big? What can I try to straighten this problem? I'd rather
not have to move the antenna if I can avoid it. Thanks.

It's not the size of the antenna, it's the way you point it! I'm sure
Richard and Hugh, (if your getting this boys), will be able to help, as well
as Shane and Joseph.

Walter,

If you have an amplifier try removing it, if not try getting attenuation
pads from radio shack (maybe) and install inline at the distribution point
or going into the STB (pads are usually 3db, 6db, 9db etc.). Radio Shack
may also have a variable attenuator. You can also try disconnecting the
antennae completely and use rabbit ears and see if that works, it also gives
you a good idea as to how much signal you have.

Do you receive other channels as well, cuz if you do it then gets
complicated as you try to balance one channel reception to another. If this
is the case you'll probably need an automatic rotor on the antennae and
tune/de-tune in combination with amplification or padding (attenuating) to
achieve the best combination for the individual channels.

This is a continuing problem with OTA reception and will become a major
problem for all who receive OTA as there only source for TV and a major
annoyance for those of us you view it because we want to.

Size does matter as well as how you use it (point it)! The bigger the
antennae and the more di-poles sized for the various wavelengths the
antennae is made to receive the higher the antennae gain.

It's probably just overloaded and the attenuator might help. If it is on a
rotor I'd first turn it 180 degrees away from the tower and then slowly
bring it back and see if that helps, if not then the attenuator and if not
that a shorter antenna with less gain. Rabbit ears just might work.

Walt, please let us know the results of your efforts. With so many of us
overengineering our systems to workaround the low power issues, it's
going to be interesting to see how many people have problems with they
turn the juice up...

Try rotating it a small amount at a time. May eliminate multipath and/or
overload and still get all the others well. That is the first thing I would
try. Let me know if that works before we go any further. Remember, turn a
few degrees (2-3)at a time.
