Tina CW1. A full postcode is preferable as to ascertain which transmitter or relay you are using in order for the true pros on here to give further assistance to you.

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 !

Come DSO at Bilsdale (BBCA DSO1,Wednesday 12 September 2012,the rest DSO2,Wednesday 26 September 2012) the new higher powered post digital switched signals of 100kw on the public service broadcasters multiplexes BBCA,D3+4 and BBCB (HD),plus the 50kw commercial multiplexes SDN,ArqA and ArqB will vastly improve reception in your locality which at present is somewhat difficult.However you stated that your aerial is directed at Bilsdale yet receive some Pontop Pike transmissions due to poor reception issues in your locality because of trees.Is your aerial that faces Bilsdale a group W wideband (tipped black) antenna by any chance ? For Bilsdale once DSO takes effect you need a group K (tipped grey) semi-wideband aerial (either Yagi 18K,or X-Beam 16K) which is optimised for the lower/middle frequency bands,fitted with superior copper-copper co-ax cable (black coloured preferred for longevity) and importantly brass co-ax plugs,not alloy or worse plastic ones they're useless.
If you decide to opt for Pontop Pike instead which also switches over simultaneously with Bilsdale too,you need either a group C/D Yagi 18C/D aerial (tipped green) or a group E semi-wideband (optimised for the middle/higher frequencies) X-Beam 16E aerial (tipped brown).One possibility is to use a variable frequency diplexer (if available),one that splits the signal at a certain frequency say for example at frequency 47 so you can effectively have two main transmitter choices,one group K aerial using Bilsdale and a second aerial either a group C/D (Yagi) or group E (X-Beam) aerial using Pontop Pike as well.
