Yes, the very approach I'm considering for two masts in the garden, one
at 20ft to support one end of a 180ft doublet, and the other at 30ft to
support some VHF/UHF antennas, a 2.4GHz fixed dish towards an VHF NFD
Contest Site (line-of-sight at 23Km!), and I'm also considering another
Dipole or Inverted-V for HF.

The 20ft mast will shadow an existing BT telegraph pole (had thought
about using it!), and shouldn't be a problem in terms of planning or
interference (well my telephone isn't connected to it), but the 30ft
mast will have to be a wind up design as I want to experiment, and
because I'm a long way down the rear garden, it could be 60ft tall and
still wouldn't be seen from the pavement at the front of the house.
30ft or 40ft would be ample here as I'm on a hill anyway, and shall only
initially be using two small beams on a rotator, for 2m and 23cms.

OK then, try to get into the neighbours' gardens and take some
photographs you can draw on.
