Directv booster or amplifier


Anyone have any experience with these? I've got close to 90 ft of cable from my dish to a splitter and then another 30 ft to my receiver to my Pioneer Elite. Got a great pic but sometimes I get some posterization or shadowing. I'm wondering if I need a booster to boost the signal, any help will be greatly appreciated.

Pops, You need a booster. I don't remember what the brand was I used to install, but after about 100' you really needed a booster-which did a good job. Install it before the splitter-sometimes you can get too strong a signal and then it does weird things to your signal/.
Hi,there Pops. ---I'm running the 100 ft to the receiver,then a long s-vhs run to the tv. What does the system signal strength meter say? I get low 90s. I also have Chang & Monster 200 s-vhs cable (4 mt run) Both of these make a "big" difference.
You can buy an non-powered amplifier at radio shack for ten bucks. They sell plug in models that are more powerful.
Thanks all, avguy I also get in the high 80's which is common around here, i use a monster s video cable, i believe the 1000 or whatever the model number. my only real complaint is the shadowing i get on dark scenes - i've never had the tv calibrated - too cheap it costs about 400 bucks and then your not supposed to move the tv. i can't commit to not ever moving the tv because i'm always switching stuff like cables around.
