Antenna spacing (TV and FM)

At present I have an exterior pole-mounted TV aerial, which gives great reception. My FM half-dipole antenna is in the loft, and is susceptible to interference from my ventilation unit. So I'm looking to mount it outside too.
I know that you shouldn't have two TV aerials close to each other, but is there any harm in mounting the FM dipole on the same pole as the TV aerial? I'm thinking in terms of reception problems caused by their proximity, not wind loading.

Re: Antenna spacing (TV and FM)

Used to see plenty with 2 or more aerials on one pole, my parents had a large FM aerial on the top of their pole and two TV aerials below (pointing to two different transmitters), all professionally installed at the same time and never had any problems - not sure if they still have 2 TV aerials since the digital changeover.

If you want to know how not to do things, spend an hour looking at these installations:
