You can get splitting devices to run two receivers from one aerial in most
dealers. I believe Argos may have them as well. They're not fancy. They're
just small boxes with a few coils and capacitors inside that make sure the
signal is divided between the two or more receivers efficiently without any
reflected signals getting in the way.

Two separate cables from the one aerial is incorrect and would not give as
good results as a proper splitter. It'd also be a waste of cable.

If you're in London, make sure the aerial is mounted horizontally and
pointed at Wrotham where the transmitter is. Phone the BBC Engineering
Department for the bearing and for general advice.

If this is too much, you could always go the whole hog and get D.A.B.

Seeing the other thread on FM and aerials has reminded me about
something I've been meaning to find out about.

I would like to have a proper FM aerial installed on the roof. The
thing is that there are two receivers that I would like to connect it
to. One is in the lounge at the front of the house and the other is in
the dining room at the back. One option would be to have the coax
coming down from the aerial, eirther at the front or the back of the
house, bring it into the house and then split it somehow. I'd rather
avoid this option to minimise internal disruption. I was wondering
instead how feasible it would be to have two separate wires coming from
the aerial - one going down to the front of the house and the other to
the back. Would this need some fancy splitter or something or could
the two coax leads simply be wired into the same aerial. (I guess
there's also the option of having two separate aerials but that seems a
bit over the top.)

In case it's relevant, I get pretty decent stereo reception already
with one of the receivers (its a hi-fi tuner component) even with the
T-shaped bit of wire that came with it, so I reckon I'm in a reasonably
strong signal areas. The other receiver gets weaker reception usually,
but I think that is partly to do with there being fewer options in
arranging its 'bit of wire' optimally because of how the room is
organised. The latter would I think particularly benefit from a proper
aerial but it would be a shame not to make use of it for the other
receiver too.

Thanks.

Be aware that that only transmits BBC stations and Classic FM, most of
London's local stations, in addition to 'filler' services of R1-4 and Classic
are transmitted from either Croydon or Crystal Palace. The latter national
services from CP are vertical polarization only, the locals (and Wrotham) are
mixed polz.

No good for serious quality listening I afraid, but it will get you extra
stations not available on FM.

Not quite. Wrotham transmits Mixed polarisation but you might find it
simpler to mount your aerial horizontally. If your in parts of South
London, Crystal palace may give you better results.

Not if your talking about hi-fi reception;(....

Absolutely. The BBC national stations from Wrotham are terrible in this
part of S London due to the hills in the way. Driving down Trinity Road
where it crosses Wandsworth Common in a traffic jam where it inches
forward results in near total cancellation of an R4 signal at times due to
extreme multipath. My current car uses diversity reception - it has two
aerials and selects the best one - but is still not perfect. The 'fill in'
transmitter at CP cures this problem totally.

John Birt when DG of the BBC used to live just off this road in the
'Toastrack'. There was no external FM aerial on his house, but a standard
UHF TV one. After a Feedback discussion on general FM reception problems I
wrote to them saying that either he never listened to BBC FM radio, had
cloth ears, or had a line feed. I have an 8 element yagi for FM on my
house and still had problems with Wrotham. A short time later we got a
fill in transmitter. ;-)
