Juliashmoolia Posted May 12, 2008 Posted May 12, 2008 I have a Dick Smiths indoor antenna with build-in amplifier (Cat No. L4016) I'm having trouble with electrical interference from lightswitches and my airconditioner. I've read other peoples posts re similar problems and from what i can tell, i can improve the problem by replacing the coax cable with RG6 Quad Sheild coax cable. Is this correct?
charlesc Posted May 12, 2008 Posted May 12, 2008 Your problem is most likely that the whole unit is picking up interference as part of the reception, through its antenna elements. And then boosting that impulse through its amp. You need to get a stronger, better quality signal in in the first place, one that has low error rates, to give you decent digital reception. I don't think RG6 cable will help if you use it to replace the L4016 lead. Or if it does, it would be marginal compared to the problem coming through the antenna pick-up.
mtv Posted May 12, 2008 Posted May 12, 2008 I doubt you can replace the cable from that antenna.... and many of the DSE indoor antennas now have good shielding on the coax anyway. The problem you have is the antenna is picking up the impulse noise interference and the amplifier, amplifies it. Amplifiers amplify noise/interference as well as signals.... this is why an outdoor antenna works better, as they usually receive more signal than interference. The higher the ratio of signal to noise, the more the receiver will reject the interference. If you have no other choice than to use an indoor antenna with an amplifier, try to position it so as it receives as strong signals as possible. You may need to use an extension cable to locate the antenna in a better position. Use RG6 Quadshield cable.
