[QUOTE="easysat, post: 18809, member: 175305"] If an extra 17m of cable is making such a difference, maybe the cable is low quality and attenuating the signal. I would try and see what grade of cable has been used: perhaps the cable type is marked on the sheath. It might be worth replacing it with top-grade satellite cable. You could measure out the required length and try it with a temporary connection before going to the trouble of fixing it to the wall, etc. As to the other question, you would be hard pressed to damage the input of a satellite receiver just by increasing the RF level with an amplifier, unless you use something for transmit applications that has seriously large amounts of gain and power. From the noise point of view, any amplifier should be close to the LNB rather than close to the receiver. Try it but I don't think it will work as well as increasing the dish size. [/QUOTE]
