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?

Dave Lindsay: Thanks for your advice to go vertical. I have solid reception on all channels.
For the record: postcode SP11 9QD, aerial points to Rowridge.

I live in the Bassett area of Southampton and have found that channels 12 and 15 have much poorer reception levels that the other channels. I have been up on a ladder and changed my Ariel position somewhat - this has resulted in rather better reception but still not as good as for example BBC1/2 or ITV. Is this usual and are these channels transmitted at a much lower power?
May thanks

John: Following the change on 18th April, you may benefit from changing your aerial from horizontal to vertical.
Rowridge is mixed polarisation. The Public Service channels are 200kW horizontally and vertically, whereas the Commercial channels are 50kW horizontally and 200kW vertically.

I am in Southampton and find that channel 12 and 15 are weak. Will I improve reception by turning my Ariel vertical? Are these channels transmitted at 50 as against 200?

Hi,
I live about 5 miles south of Winchester in a Park Home. My ariel is horizontal, pointing to Rowridge. A couple of days ago the Film4 was very bad, almost unwatchable. It was worse everytime a plane took off from Southampton Airport northwards towards Winchester. Would VP be better

Terry: Yes, vertical will be better as all signals are the same power vertically.
Horizontally the Commercial multiplexes (which include Film 4) are weaker than the Public Services ones (BBC, ITV1, C4, C5 etc).

Terry,Winchester.As Dave Lindsay rightfully states vertical polarisation is the better option.However if i may add is your aerial a group A (coloured red at its tips) type,or a group W wideband (coloured black at its tips) aerial.Group W wideband aerials unless residing in a good/medium reception area on an all group A transmitter perform badly on all group A frequencies,especially more so on an all group A transmitter within Rowridge itself in a poor reception/marginal area.Check the colour tips of your aerial at the same time you realign the polarity from horizontal to vertical,that you are using the right aerial red tipped group A and not the wrong aerial black tipped group W wideband for all group A mast Rowridge in a poor/marginal area itself.

Terry, Mark Fletcher: I think even if Terry's aerial is a wideband, that it will work if it has worked before, which it clearly has.
Whilst it is true that the gain of wideband yagi aerials is lower on Group A channels, if it has been proven to work, then I see no reason to replace it.
I think that one of the main issues that Terry and other users of Rowridge have to contend with is the fact that the Commercial multiplexes are only 50kW horizontally whereas they are 200kW vertically (and the Public Service channels are 200kW vertically and horizontally).
So there is a marked difference in strength horizontally and this is probably the biggest issue.

I'll give it a go.
I'll also check alignment with a Maplin A55HJ Aerial Signal Strength Meter which I have
