Aerial right way up, no better
 
You may remember my recent query about an aerial that had appeared to
deteriorate. Well I have 'fixed' everything about it, it has all F
connectors (where there are any) on the way down, it has better co-ax
for the couple of bits that weren't good quality, it's now the right
way up and I have cleaned up the balun and tied the downlead to the
mast etc.

..... and it has made very little difference at all. In fact the
performance on ITV (channel 56) has improved quite a bit, but the
performance on BBC1, BBC2 etc. (channel 49) is now absolute crap.

I get the feeling my aerial must be sitting in an area full of
reflections, second path, etc., etc.

I found that sticking a rubbish 'contract' aerial out of a window
lower than the 'proper' aerial gave better BBC1 reception.

I suspect that the recent significant deterioration may be due to new
leaves growing and that the better BBC1 reception lower down may just
be 'looking through' less leafy areas.

It's probably been said already, but the location and height plays such a
big role in obtaining good reception through trees. You'd be much better off
getting someone in with proper test equipment, or hire a meter if you want
to have a go yourself. Otherwise you're just flying blind.

I think he said he'd made an investment in Freeview equipment didn't he?

Otherwise Freesat would be a good choice....

Perhaps he too has more than one TV and recorder?

I'm a fan of satellite, but for the foreseeable future they'll have to be an
aerial on this house.

All this is quite normal when there are trees in the way. Anyone with an
analyser and half a brain could find the best location for the aerial for
you in no time.

See my long follow-up to my original posting. It didn't need a signal
analyser it needed a bit of thinking and a realisation that the
original aerial was pointing in the wrong direction.

Actually *some* STBs do give enough diagnostics to use as a cheap
signal strength meter at least. I used a Philips STB which gives bar
graphs of signal strength and quality, it refreshed frequently enough
to be usable though obviously not as nice as an analogue meter. Set
up so the TV screen can be seen from where you are playing with the
aerial and with the remote to change channels as necessary it worked
quite well.

Once I'd twigged that our location really *isn't* marginal it all
became a lot easier! :-)

Although don't forget you need to check reception of every mux, not just the
one which is indicated on the STB signal bar.

Not long ago I was asked to have a look at a problem where reception had
'always been terrible. It's the power station chimneys, they block the
signal.' In fact the signal came from Emley Moor, which was at least 10deg
to one side of the power station, and when I replaced the large high gain
Group A aerial for a much smaller Group B one (!) reception became perfect.

Oh yes, I checked all the MUXs, they now do much as one would expect
in terms of signal versus frequency whereas before (when presumably I
was receiving a refracted/reflected signal) their strength had very
little relationship to their frequency.

So someone installed a group A aerial for Emley? They should bring
back the death penalty for that! Incorrect aerial usage = instant
death. That should shake up the aerial erectors market a bit :-)

I think the death penalty is a bit harsh, maybe life in prison.

Where they'll likely have the benefit of TV system installed by
you-know-who. Provided they learn from that how it should be done, of
course!

I think the installer had assumed that he'd have to use Belmont. Apparently
there's been a session of 'trying it the other way'. Having failed with
Belmont he'd just swung it round to Emley and buggered off.
