Sorry for the OT post but would really appreciate the advice,and I know
people here will have the answer...

I've just received a text message from a friend who's working in the
Middle East today doing repair work on big radio masts. He's just been
sent 50m up a mast with live microwaves (for mobile phones), with VHF
radio transmission for TV and radio on the same mast 50m above that;
having been assured it was perfectly safe to do so but has subsequently
found out that this was pure supposition. Ha bloody ha.

If he only got as far as the mobile phone bit and didn't hang about in front
of a microwave link i don't see there is a problem.
In general the power is radiated away from the mast so being inside or below
it means low power levels.
