Um yes.... and polarised horizontally or vertically and some aerials are also 
'tuned' to just pick up some frequencies (and thus cut out more 
interference). I did have a nice link somewhere about the aerial types... but 
googling will probably get the information quicker.

I tried a few different aerials and ended up with a simple maxview wideband 
one with an amp, that picked up the best signal for me.

The ofcom site has a list of transmitters and frequencies:

There, crystal palace is horizontal and guildford is vertical.
