For some reason this web site keeps showing my transmitter as Salisbury. This is wrong. I am on Rowridge, Salisbury, though closer, offers no advantage over Rowridge in my location.

Took advantage of yesterday's fine weather spell to realign aerial to vertical polarity and replace cable to MHA. The cable was the main fault. Cracked in several places with broken braiding in one place, with the cable just hanging on the central conductor. Rain obviously completed the circuit to enable days of good signal strength and quality on all muxes!
What mystifies me is why, throughout, the BBC Channel 24 mux remained good signal strength and quality. To quote the aerialsandtv.com web site "RF reception really is a black art, not a science"!

OK, what's been going on. For the past 6-7 weeks (since the first high winds in December) I have had variable, usually terrible, reception on all Rowridge muxes, except BBCA on Channel 24. That has been OK for 90% of the time. It has affected all my TVs (4 plus Humax), fed from a horizontal aerial through a MHA. My location is SP6 2HA, where there is no direct line of sight to any transmitter.
I began to think it was my rooftop system playing up (areial, cable, amplifier). I have arranged for the aerial to be realigned to vertical and the cable replaced with copper/copper/copper, but that has yet to be carried out.
Then suddenly, today, I have 60% plus signal strength and 100% quality on all muxes. I have changed nothing, the weather has not changed, my line of sight has not changed. Could it be the problem has been with the transmitter itself and the engineering work this week has rectified a hitherto unrecognised fault?
