Yes if you're worried about obese pigeons dislodging your horizontally polarised aerial down yer chimney then yes switch the polarity to vertical,also make sure your aerial is a group A type (tipped red) if you reside in a poor/marginal area within Rowridge itself.One further advantage about vertical polarity on Rowridge is the more stable reception you will receive on the commercial multiplexes,SDN,ArqA & ArqB as it is broadcast on 200kw,compared to 50kw on horizontal polarity on the commercial multiplexes only which i stated above.
Yes go for vertical i say !

Help,please.In Winchester,Roof aerial points to Rowridge,horizontal polarity,Sony Bravia tv.I can get all muxes except ArqA. All at high signal but missing one.Retuning by auto or manual methods give same result ie no trace of com5(ArqA.) Tried single channel interference from vcr as aerial loops through. no difference.Is attenuation worth trying?. Before I risk life and limb on the roof trying out vertical polarity or has anyone any suggestions. Problem is driving me bonkers.

Ted Hopper: Attenuation is probably the only thing you can try.
There is the possibility that some of the problem is interference from another transmitter which attenuation won't fix and which polarising your aerial vertically will probably help.

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
