Antenna Update

----- HDTV Magazine Tips List -----

Going from 400 kw to 1 megawatt is an increase of approximately 3 dB in
RF power. I would guess that the rest of the channels you are receiving
have a signal margin of greater than 3 dB. An easy fix might be to buy a
3 dB in-line attenuator, which would knock down the CBS signal to
previous levels and probably still maintain reception on the other
channels. These attenuators are cheap (about $2), so you won't be out
much money. You can find them on line @ www.partsexpress.com or maybe
at your local Radio Shack or electronics store.

Hi,
I thought I would update my antenna trouble and seek a little more
advice. To refresh everyone's memory, my local CBS station recently
upgraded their power from 400kw to a full megawatt. This caused me to
start experiencing frequent dropouts, whereas the signal had been
practically perfect before. So far I've tried using a small indoor
antenna, unplugging the preamp, and using a variable attenuator. None of

this worked.What I want to try now is adding a channel 46 block to my
main antenna and using a smaller dedicated antenna with a channel 46
pass-through to get this channel. Anyone know where I can find the parts

online? Thanks.

Walt

Do these work better than the variable attenuators? I tried a RS
variable att. (0-20db) with no improvement. My local RS didn't have the
3db or 6db in-line models.

Probably not. Where in the circuit path did you insert the attenuator?
You indicated that you have a preamp. Did you insert the attenuator
before or after the preamp? If you inserted it before the preamp and
found that it did not have any effect, I would say that the 1 megawatt
power level is not your problem. If you inserted it after, then maybe
the preamp is saturating causing signal distortion. Attenuating a
distorted signal would not correct the problem.
