Prime 7 Black Mountain Glitching?
Posted 11 March 2013 - 03:08 PM
Happy to accept it is just us, perhaps interference from a local source?
Thanks and cheers

Black Mountain is pretty immune to these kind of things as both Prime7 and SC10 HQs are in Watson, ACT. And both have receive antennas pointed towards Black Mountain. If there was a problem, someone would be all over it within hours.
Prime is usually the weakest on a standard X-Polarised combo antenna without a standoff bar. Which may be all thats required if the glitching is minor. This is due to self-interference from the mast.
Hard to know what is actually causing the problem without a signal meter onsite.

Could it simply be that the antenna simple isn't up to scratch for digital, and has given up the ghost?
Apologies for my ignorance.
Thanks for any help.

The antenna should be fine for digital, being so old it was cut for channels 5-11 instead of 6-12, but to the best of my knowledge the newer models are the same size anyway and therefore make no difference.
As to why your Prime is poor, its hard to say without readings onsite. There could be a number of reasons, and they could all be quite weak, just that Prime is a little bit worse.
Given the age, id be worried about the structural integrity of the balun/s, and the resultant corrosion from water ingress..
* This, and this (or similar) - combined in a little box on the mast or in the roofspace.

Sounds like new antenna may be the go if going to the trouble of replacing the baluns.
Your advice is gratefully received and appreciated :-)

Random SQ errors which seem to stabilise and then plays up. This is now after antenna has been replaced. Mind you the old one was rusted, full of water etc.
Cant help thinking there is some local interference but have checked with neighbours and they dont seem to have a problem. So will inspect cabling in roof next as best I can.
