Thanks for the feedback guys. I am using RG6 (about 75ft) ... I guess my only option to increase the signal level is to get a larger dish (my current dish is 30" on short access) 1 meter (41") would be perfect but its so expensive especially the shipping ...Iam trying to find something locally but no success .. I live in Phoenix,AZ
Guy FTA,
You should have no problems with 75 feet of cable if it is quality cable. As Ice has mentioned, he has a 100 foot run and has no problems. I have also set up a dish about 210 feet or so away from the receiver with RG6 cable and had no problems controlling the motor, switches and LNBF.
As Sadoun suggested, using RG6 or RG11 cable with a solid copper core would be better than CCS (copper clad steel), but if you are having signal QUALITY issues with only 75 feet of RG6 cable, you likely have other problems and as Ice stated, the amplifier won't help you much.
You either have a really poor cable/connection, the dish is not perfectly aligned for this particular satellite or the satellite signal is very weak in your location and a larger dish (as Sadoun mentioned) may be required.
If you take your receiver and a small TV directly to your dish antenna and check the signal level and quality using a very short segment of cable, you can verify whether the 75' of cable is a part of your problem or not.
If the signal does not improve greatly when you are right at the dish, then check your alignments first and check the EIRP for that particular sat and TP for your area and verify that you have the appropriate sized dish (or not).
