Steve,
I'm struggling with a poor set of options for an aerial at this house.
The
greatest vertical section I can get while still allowing top loading is
8-9m, but the lower 3-4m would be up against brickwork. How much does
this
affect radiation compared with, say, 6m vertical clear of buildings (with
the same toploading)?
It's fun trying, even if proximity effect robs you of a few dB. Give it a
go, assess results and then decide what betterment route to take.
Unfortunately, limited spare time and circumstances make aerial experiments
difficult - I'm going to have to live with whatever I choose for some time.
From G3XDV:
It depends what you mean by "up against". Good insulation is vital, but
assuming you mean 100mm or more separation, there should be little problem.
Up against pretty much means up against, although after reading your
comments I'll see if I can work in some space. Very helpful, thanks.

A Freudian slip? :-)
