Splitter/Combiner works but...

[HUGHP]

getting "fuzzy" DirectTv satellite reception. Took out the selection box so the wife can switch beetween Sat. and locals in the bedroom without walking upfront to the box. The local reception is perfect. Is there some sort of filter I can put inline to get a clearer picture from the Sat. receiver? Other solutions?

Once you removed the video switcher, how you are now sending the signal to the back TV? Something has to act as a switch if you are using the same cable to 2 different signals.

Both signals come in strong with just this Channel Plus 2534 Splitter Combiner 4-Way 1 GHz Video Signal Bi-Directional Coaxial DC Block Coax Cable Splitter UHF / VHF TV Antenna Combiner, 5-1000 MHz, Part # 2534: Oak Entertainment Centers and Home Office Furniture, TV Antennas, Audio/Video, Sa

Two things I will tell you:

1: Those splitter/combiners often have serious loss issues, some of them are decent (3db is the minimum loss) some are, well, I've seen loss figures in excess of six Db that that's a lot of 10th's of a Bell let me tell you.

Second: the coax cable in many RV's that runs front to back.. Not the best cable on the shelf. Though usually the Chan-3/4 output of the DirecTV receiver is processed well (They get worse as frequency increases as a rule)

Now, I have one splitter/combiner here that more or less kills VHF though, lets UHF thorugh, ok, but VHF is toast.. I had it in line for a while. When I removed it.. WOW did things improve.

Is that splitter/combiner you are using by any chance a "Diplexer"?

The Direct Sat signal is perfect when the antenna input is disconnected from the combiner. Also all signals are fine coming thru the selection box. Just trying to save the boss lady some steps.

You might be better off reconnecting the switcher box and offer to push the button for her!

I isolated where the interference is coming from when I switched the antenna booster off. Now,wonder how one could filter that?

[Bill Adams]

The booster is not a booster but rather a 12V power supply. With this on 12V power is sent through the coax up to the TV antenna on the roof where the booster is located. When you turn that off it works like and A/B switch and allows the cable coax connection to be operational. Without the 12V power going to the roof you will not get a TV signal so it's not something you want to filter.
