I get ghosting because I'm in Wollstonecraft. Lots of signal reflection.

Indeed. You'll get no argument from anyone around here.

Those near the water need a bout 100m high mast to get a direct line of
sight.

Not quite 100m but very nearly.

Digital eleminates the visual disturbance, but the effect is still there
in the signal, waiting to cause trouble.
Since signal reflection doesn't seem to affect digital signals,

** Nonsense - it does.

It may but I am yet to notice it compared to the analog signals. The digital
ones are almost crystal clear in comparison.

The DTV signal format is almost immune to moderate ghosting effects - but
severe ghosting will still mangle it.

OK.

what would cause helicopters passing overhead to interfere?

** Two things - severe ghosting & severe and rapid signal level
modulation, you can see the latter on the on screen bar graph that most DTV
tuners provide.

My TV was automatic. When I first turned it on, it spent well over 20 minutes
automatically tuning every signal it could find. Including all the South Coast
ones. I'm not aware of any bar graph. That's not to say it doesn't have one. I
just haven't gone looking since there's no need.

An overhead chopper ( in the right spot) could easily be a stronger signal
source for your antenna than the TV transmitter - acting like a wobbly,
rotating mirror in the sky for VHF and UHF energy. Mangles anything.

Everything to do with TV reception directly relates to the particular
geographic location, installation and type of antenna in use. Means that
reception problems can normally only be fixed by on-site inspection and
assessment by an experienced antenna tech - then some experiments to see
what works.

The latter is especially true in problem locations like yours.

BTW:

Once you have a decent signal available on all channels, annoying glitches
from light switches etc will likely disappear.

Unfortunately, DTV is *not immune* to electrical impulse noise caused by
arcing switches.

The switch in the bathroom is particularly annoying because it also interferes
with my wireless modem signal.

them for $0.80.

your helicopter problem is common with VHF and UHF signals. Your
antenna is recieving multiple path signals where the out of phase
signals cause cancellation and signal loss.

And the solution is a higher gain antenna, which will be more directional.
