[QUOTE="spiney, post: 151471, member: 192438"] inline amps are normally used only to boost signal levels on a very long cable run, where input levels become too low for the satellite receiver to work. Otherwise, note that any added amp will increase bit error rate, ie lower the "signal quality", so your reception will actually get worse! If bad reception now, the only answer is to improve it, possibly by using a lower noise type lnb. There are also various cable types, some have a lower loss. Check the lnb connection, this can degrade over time, if necessary replace the f plug on the cable end. "Compensate for impedence" is gibberish! All lnbs/sat-cables/receivers have the same nominal impedence of 75 Ohms. [/QUOTE]
