I currently have a setup for receiving DTV. My antenna system uses 2 inline boosters. For some strange reason sometimes only the stations with the strongest signals come in. I have to disconnect the coax from my first booster and reconnect it again and the rest of the stations that I normally get come back in.
Anyone got any ideas why?

Yep - the booster may not be designed for the type and frequency of the DTV signals. Also with two boosters you maybe overdriving the DTV converter/receiver and causing it to loose the wanted signal underneath a strong off channel signal.

If you get good reception with only one booster amp, then permanently remove the other one..

Thanks for you answer. I need a second one because further down the line I have a splitter feeding 2 additional tvs, 3 tvs total. My first booster feeds to my first tv and to the second booster.
The first booters specs are SWS2081W/17
Forward Path 54-1000 MHz/Return Path 5-42 MHz

PLace the second booster after the splitter and see what happens

Unless your TV signal boosters are perfectly linear, they will not work properly with DTV signals.

I split my DTV antenna feed 2 ways, no boosters, and I live about 60 miles away from the closest DTV transmitter. I am 100+ miles from some others, and they all come in just fine.

Bowtie stacked antenna @ 40 feet AGL. 85 feet of RG-6 coax.

The first DTV booster that I used said it was dtv compatible and I often have the second booster turned off. I guess its a miracle that my system works at all cause my antenna is a cb diapole antenna in the attic(it actually worked better than my vhf/uhf scanner antena).
