The symbol shows the location of the Rowridge (Isle Of Wight, England) transmitter which serves 620,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Rowridge (Isle Of Wight, England) mast?

Geoff Smith,
Phew. At least one of you is having problems! It does make you go running around trying to fault find, probably pointlessly? I have rechecked all my connections but all 4 Freeview devices over the house are getting poorer signal strength this morning, certainly lots of digital breakups. I hope you are right about Rowridge having some problems! I am already on vertical polarisation and was getting good signal strength without the need any of the 3 boosters I had in circuit before 21 March. And virtually no digital breakups until this morning.
I am wondering whether it is co-channel interference yet again. I had hoped with the increase in power to 200kW on all vertical polarised multiplexes that this would be really minimised but perhaps not? I must go and have have look where the nearest high pressure zone is..... off to have a look on Met Office site!!!

Geoff Smith: If you are attempting to receive Rowridge in Haslemere then its COMs are co-channels with Haslemere's PSBs which are also co-channel with Crystal Palace's COMs.
Rowridge now broadcasts vertically as well as horizontally. 200kW for PSBs vertically and horizonatally. 50kW for COMs horizontally and 200kW for COMs vertically.

Phil K: Stockland Hill's COMs are co-channel with those of Rowridge. Last night they had a power increase so you could be getting interference from them. You may have to switch your aerial to vertical to reduce the chance of such interference as well as picking up stronger COM signals from Rowridge.

Dave Lindsay: Hi Dave...appreciate what you say but geographically we are 1 and a half miles south of Haslemere and our aerial (A type horizontal) is pointed south west directly towards Rowridge. There is no chance that we receive any transmission from the Haslemere relay which is directly North East of us and obscured by Blackdown Hill.
Suffice to say that since I replied to Derek Green all of our channels are up and running again. However we do seem to be a slave of weather conditions and will probably have the aerial vertically positioned to get full advantage of the new power 200kw COMs increase. Thanks for your advice..be blooming glad when all these changes are over and done with!

Derek Green: Hi again Derek....all channels seem to have stabilised and are back up and running. I'd be interested to know whether yours have improved as well?
Cheers

Sean Marshall: The signal strength is not the main factor with digital reception; it is quality. So long as the strength is great enough to produce give "good" reliable quality, then I suggest that you do nothing with your aerial if you will have to pay someone to make any changes.
Directional aerials by their nature are more sensitive in one direction and less so in others. So if the interfering signal is coming from a direction at which your aerial is least sensitive then it will produce less interference to your receiver than had it been from a direction where your aerial is more sensitive.
So don't read the Tradeview predictor as being what you will actually get. It is simply a guide.
If your aerial happens to be in a spot where it picks up no signal from Crystal Palace then it will endure less interference than had it been in a location where it got a little. Such a difference could be metres.
Clearly the only way to give a definitive answer is to measure the signal levels on-site. On the basis that this will cost and that you already have an aerial, I suggest, just as the response from Digital UK says, that you leave it and see.
Should you find that you have an issue, then you are now briefed on the possible cause and possible solution.

Ref Rowridge transmissions. Can you say if the horizontal SDN, COM 5 and 6 muxes are to remain at 50KW or will they be eventually be upgraded to 200KW. I ask because CH22 and 28 are at the edges of gain of my indoor antenna and have marginal signals since the switch this morning (18th April).
I may have to go to vertical polarisation.
Thankyou

Peter Ball: I can confirm that all of the multiplexes are now at their final levels.
Indoor aerials are not really suitable for reliable Freeview reception. However, you can probably be sure that if you nearly have reception with one, that a rooftop aerial would provide totally stable reception.

Geoff Smith,
I have just had the oddest experience. The signal strength was definitely down this morning, but I discovered that the 4 outlet distribution amp in my loft (which is over 15 years old!) had finally gone weird! The signal strength was 90% but the quality on all channels was varying wildly between 40 and 100%. I have just replaced it with a new one from B & Q (£14.99 for a complete aerial distribution kit with all sorts of cables, plugs etc that I did not need!!! but it was the cheapest option) and all the issues have gone away. There are still occasional digital glitches but very minor ones which I am assuming is due to the weather.... But I am back and running with 113 channels including all 4 HD ones.
