[QUOTE="moonbase, post: 1122495, member: 178786"] I compared the signal levels from some joined coaxial cable and direct coax cable and the loss was only fractions of a dB on a 25 metre run. Out of choice I prefer to use Webro 100 coax cable and have found it to be OK for cable runs up to 45 metres. The cable with wires for motors/CCTV might be a hybrid cable with thicker cores for the motor current and thinner cores for the sensor. If it is only the thinner cored cable I think it might be classed as sensor cable but the cable guru's are the experts on this. Personally, I use 4 core cable with core thichness of 1mm for each core, two cores for the motor and two for the pulse/sensor. I have not bothered with extra shielding around the sensor cores and have had no glitches or false pulse counts in years of use. If you are buying some, get the cable with rubber outer sheath. Just a suggestion, why not create your own "Motorised 1.8m Channel Master Installation" topic and group everything in there that is related to the install such as paint, wiring, concrete base, etc It would aggregate everything in one place.
