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

I'm back
Firstly the aerial.
No coloured tips. All plastic mounts are black and brittle!!!!!!
Turned the elements vertical and tested.
Got occasional flickers on the 70dB led.
Hooked up TV lead and checked TV. Best signal quality I've ever had on Film4 and Really, which have always been pretty weak.
Picture ok for now but I think that a new aerial is on the cardsTerry

Terry: If you have a booster, then try removing it. Keep the aerial vertical as that is definately the best for Rowridge.

Terry: If you do decide to get another aerial, you might like to take a look at Rowridge Transmitter

Terry,Winchester.The aerial you stated appears to be an inferior group W wideband contract aerial.If you decide that a new aerial is on the cards then replace with a superior group A (red coloured tips) antenna,preferably at your location a Yagi 18A polarised vertically,with at the same time new superior copper-copper black coloured co-ax cable and importantly superior brass co-ax aerial plug.I would strongly recommend looking up the ATV (Aerials and Television) of Sheffield website,believe me they are the No1 UK aerial accessories retailer and the best,forget the rest.

Dave Lindsay: something you mentioned at the time when I asked for help:
interference from other transmitters: it is worth checking that the right channels are being selected. One of my freeview sets needed to be tuned manually.

Ray: Yes, sometimes the automatic tuning procedure can leave the wrong transmitter tuned in.
Hannington and maybe Midhurst look as though they may be possibilities for you. Perhaps swapping to vertical polarisation would also reduce the likelihood of that happening as they are horizontal only.
Looking at the channel allocations for these transmitters, you should be able to unplug the aerial lead at 30% so as to scan Rowridge's channels and avoid those of Hannington and Midhurst.
