Does anyone know where I can get right-angled plugs for television coaxial
cable? I've a couple of places where coming straight out from the wall
socket is not suitable. I've tried Maplins, Screwfix and B&Q. Maxview's
website doesn't show anything like that.

Alternatively a made up fly-lead with right-angled plugs would be OK.

Check out this web site:

Products "MK K3520", "MK K3522" or "MK K3523" might do the trick.
These are TV aerial sockets which are pointed downwards at about 45
degrees (can't see the angle from the picture).

Yes it is plugs I'm after - I wired all the bedrooms a couple of years ago
when I decorated, and put in flat sockets. The problem is that now with
change arounds, a couple are behind beds and cupboards.

I'm not sure you'd gain very much - a Belling lee plug is about as small
as they come. Other plugs designed to be constantly removed and replaced
have a cord grip which makes them relatively longer.

I read it. So what's the big problem using straight plugs which go
into a socket angled downwards then?

From the original posters enquiry:

That doesn't tell me that the solution has to be right angled plugs!

I happen to think that the sockets I suggested earlier (which point
downwards) might take up less room when used with a regular plug, than
having a right-angled plug.

I'm not sure that right-angled plugs exist anyway - though I'll be
happy to be corrected. The reason I say this is because when you get
into RF frequencies (which you do with TV signals) any kinks in the
cable run can lead to unfortunate stray signals - a bit like if you
have a pond with a stone standing out and you send a ripple across the
water - when it hits the stone you get all sorts of ripple patterns on
the surface.

I remember an experiment in my HNC Electronics course years ago where
a coiled cable was used, and terminating the cable at different places
made a hell of a difference to its usefulness! The signals went from
dead clean to highly corrupted just by moving the measurement point a
very short distance.

What happens is that the RF signal goes along the wire and if it is
properly terminated then all the energy is absorbed at the far end. If
not properly terminated (or kinked) then some of the energy bounces
back along the cable, degrading the quality of the signal due to
noise.

But, I do not claim to be expert in this arena so if someone at the
back shouts "rubbish!" please accept my apologies for wasting
bandwidth

Think that's the idea of a right angle plug - to prevent kinks in the
co-ax.

50 ohm BNCs (RF impedance) certainly exist.

I'm not sure if this helps, but I've got oulets witha 45 deg down anle on
them, thet've gone now, replaced with upgly straight ones by aerial
installer because they weren't DC, (and I reckon he walked off with them)
of course given time to think I could have bypassed the capacitors, but you
know how it is with a gorilla in your front room....

Any how, they do exist and aren't that all hard to find

Except that (I thought) coax for TV is 75 ohms

I think you might find that the connectors are designed to minimise
reflections. Right angled connectors are used well above V carrier
frequencies

The only reason I'm looking for plugs is because the sockets are already
wired and fitted in place (as it turns out, now the wrong place). I do know
they exist (or at least did), because I already have two in other parts of
the house - the difficulty I have is finding some now. But, from another
reply, it looks like CPC have some.

Yes. However, with BNCs, 75 ohm seems to be reserved for baseband video
and some audio. RF tends to be 50. Don't ask me why. ;-)

Normally very good ... as long as they have them in stock

Yes if your cable is seriously kinky...

No your quite correct its due to standing waves on the cable which as
you also say is due to incorrect cable-aerial-tv-whatever matching..

Actually the old belling lee coax plug is a heap of c**p the F type is
much better IMHO....

It is so get 75ohm BNCs. They exist and in right angle formats.
Baseband video is 75ohm.

But your UHF radio mics use 50 ohm. ;-) Think if you look at the spec, 75
ohm BNCs aren't suitable for HF.

And BNCs are overkill for a TV aerial socket which rarely gets unplugged.
