OTA Antenna amplifier causing 622 weirdness?

[adavis720]

With all the folks having issues with the latest software update causing their OTA to act up, I am having a hard time troubleshooting here.

My 622 totally locked up after tuning to an OTA channel, it might be a coincidence, but I figured I should ask - Can an amplifier mess up the 622? I am trying to share my indoor antenna output to the 622, my OTA STB and my TV, and using a splitter (even two-way) is just enough signal loss to make it a problem. Should I be concerned?

it shuld not. i have have 25db to boost my antenna signal then i have second 25db amp I'm ruining 622 in single mode 625 in single mode and antenna through r way splitter o combined it then splitting it 4 way to 4 TVs

I have my ota set with an amp then to a four way amplifed splitter then to two 622's and a couple of tv's with no problems.

Thanks, that makes me feel a little better. It is a 4 way amplified switch, so I guess if I needed to, I could send the output of the amp that feeds the 622 through a splitter to "dumb" it down a little.

But if you guy think it is not a problem, thats cool. Like I said, it could just be a coincidence.

Before one of the recent upgrades I had occasional problems with my CBS affiiliate pixelating when viewed through the 622. Somewhat less often it would just drop out. It never happened on the other stations. So yes I think that under some circumstances a 622 can misbehave on too stronga signal. Is the amp adjustable? other wise try the splitter or an attenuator.

Yes it is adjustable, but adjusted all the way down. I am most worried about causing actual physical damage to the electronic components, not such much just losing the signal.

My OTA box and TV seem to be doing great with the amplified splitter, I'm going to try the regular -3.5 splitter for the 622 to take a little off.


UPDATE: That seems to help, no more 100 on channel 6 (that was the one that was slamming), now in the 80's. Time will tell..

Amplification won't hurt the unit.

RF amplification won't damage the components. It can overload the 622's signal input amplifier but that will just destroy the signal.

I found that an amplifier killed one of my over-the-air channels unless I activated the FM Trap.
