Coaxial Cable
Coaxial Cable
(OP)
I am having problems with a coaxial cable television. The TV is mounted over a refridgerator. The reception of some channels is good, but the reception of some of the lower channels is very poor to nonexistant. Is the refridgerator interfereing with the reception, and if so, what steps can be taken to minimize the interference.

Refrigerators with on/off control are not continuous interferers. Only those with variable compressor speed control, i.e. with VFD built in.

I think John’s TV does not have an aerial so there is no possibility of the metal body of the refrigerator blocking or reflecting the radio waves. Metal does not tend to absorb radio waves in any case.
John,
what sort of cable TV is this? Are you on some sort of "home made" communal feed distribution system, or is it proper single subscriber cable TV? I would have thought that for cable TV you would just get the supplier to sort it out. For other sources then the most obvious things to try are turning the fridge off, as suggested earlier, and/or moving the TV elsewhere. If the cable feed is long then higher frequency signals will get attenuated more than lower frequencies. More likely however is that any communal antenna/amplifier is running slightly out of band and the gain is dropping off.

Is the coax in a good condition? Interference more likely appears in the low channels, when the cable connection isn't good.
