Use a masthead amplifier/splitter and send the power to it up the
downlead from one of the TV points.

Don't. They amplify all the **** as well as what you want and they
fail.

Get 3 decent antennas stuck up there. Maplin do some excellent wideband
ones. They do a 71 element one which is extremely directional with a
good high gain.

To the OP, ignore this silly advice. I'm a pro rigger and this guy is either
winding everyone up by posting deliberately poor advice, or he's clueless!
Just for reference, the aerials he's recommended (pictured here
http://images.maplin.co.uk/full/a20hg.jpg) are £39.99 EACH (x3). So
forgetting the difficult mounting arrangemnets required, and how bloody
awful it would look with 3 of these hanging from your house - the financial
cost alone would be prohibitive. Their design is also poor. The plastic
becomes brittle after a few months outside and snaps, causing the elements
to gradually drop off.

Bills advice is good. A good quality grouped aerial installed properly, with
some benchmarked cable to replace the old stuff. Give it a while running the
12db attenuator & you'll know if you need an amplifier or not. Total cost
will be far less than the above suggestion & it will look much neater. Job
done.

F-types seem to be a bit less of a lottery when comes to mating,
ordinary TV plugs seem to be rather variable in their quality if you
can't find any with one of the usual brands on them.

Yes, there are some dreadful products on the market. Some don't even seem
to
have the correct diameter outer connector.

Bill

The body of a standard coax plug has a mating surface 9.5mm in diameter
but there is another variant, used only/mainly in France IIRC which has
is only 9mm in diameter.

I'm sure I've seen these on some of Taylor's range in the past, with an
additional sleeve over the body to make up the 0.5mm difference. There
is a warning label telling you NOT to remove it!
That's standard on the imported filters.

Ok, now I'll be serious. Firstly, ignore everything said by Mr Conor.
His
advice is worse than useless. I don't know what motivates him, but
everything he says is wrong.

Bull****.

Shall we try "you're a **** stained old ******" for a start?

I think your reply above helps prove Bill's assertion that what you
write is worse than useless and wrong

Yes. I don't think I'm all that **** stained. Not bad really for an old
bloke.

Thank you Mr Carpy. It appears that Mr Conor is entirely discredited now,
and can be ignored.

Just one more question before I go ahead and order everything:

According to the DigitalUK website the current aerial group is E & H, but
after the switchover in 2011 this will be groups B and H. Assuming that I
follow Bill's advice and install an E group aerial (say SR18E), will it
still be ok after 2011?

Yes, the E group contains the B group, as follows:

Gp Cap clr Channel Range
A Red 21 to 37
B Yellow 35 to 53
C/D Green 48 to 68
E Brown 35 to 68
K Grey 21 to 48
W Black/None 21 to 68 - that is, all of them, aka WideBand

Thank you Mr Carpy. It appears that Mr Conor is entirely discredited now,

Him and little Jamie would be ideal for each other. Perhaps we could attach
them to opposite ends of a very long elastic band stretched along the M62
and then let go.
The splat would be worth seeing, preferably from somewhere out of the way
of the mess, such as the top of Emley Moor.

Good advice from Java Jive - all will be fine.
H just means that the aerial rods should be horizontal for your transmitter.
Sometimes they need to be vertically polarized for relay stations.

Yes, the extension of frequency coverage from 730MHz (ish) to 860MHz (ish)
has little effect on the Gp B performance. The problem with wideband aerials
is when they have to include Gp A.

By the way some suppliers don't keep Blake Gp E aerials, and some of Blake's
staff don't seem to know that they exist, but in fact they do. Don't buy the
cheap Blake 18 ele. You want the SR18.

Triax do a Group E if you can find one.

I spoke to Blake today, and they put me in the direction of a local
distributer that they claimed could get me anything they make. I'll pay them
a visit later in the week.

Can't see it on their website...
