I have a 90cm Gregorian motorised dish that has given excellent service for the last 13-years. Whilst its been working, I've not really kept pace with current receiver hardware.
Unfortunately, a dumb builder has damaged the two-wire cable to the ferrite (magnetic) polarizer mainly used in the good old D2Mac days for left/right polarized channels at 1 & 5deg West, but still of use to skew and maximize the signal for difficult satellites. I recently changed the LNB thinking it had gone, before finding the broken polarizer cable.
The question. Is it worth rewiring (about 15-metres of cable up to the roof), or would most people now just remove the polarizer?
My suspicion is that newer receivers won't know what to do with a polarizer, so it will be academic if (or when) the old EchoStar AD3000P fails. As it is, I expect the non-DiseQc motor drive (36V direct drive with optical position sensors) is likely to cause enough problems with a new receiver.
