Default Which STB for weaker ch55 mux?

Just had aerial work to enable freeview reception. (from sutton coldfield)

All muxes are strong apart from the ch55 mux, so which box(es) would folks
suggest?

The bloke recommeded the 100 Sony vdx800 as the best all-rounder, but then
again it should be for the price.

The Panasonic tcut41 (out of stock at argos at half price- there's a
surprise) was recommended from the group, and so was a certain Humax but
which one?!

Guys, its over to you ...

TIA

Check your aerial. It could be that it's the wrong group, as ch55 is outside
the old grouping for Sutton

Your Aerial is probably a Group B unless you have changed it. Group B is
from 35 to 53. Since 55 is outside this and aerial gain can drop quite
quickly as the frequency increases, you should replace it with a
Wideband or Group E aerial.

I was using a group B trained on Bishops Castle (shropshire) to receive
analogue 1-4. We have clear path to Sutton Coldfield, as the Wrekin was not
good enough.

We are now using a 18db W band aerial with a 22db W band mast head amp.
Analogue 1-5 come in crystal clear, and all the muxes too, showing 60-80%
quality on the onscreen display of the engineers STB.

Ch55 mux was only around 25-30%, thus I am looking to buy a STB which is
more sensitive than maybe some other brands...

Tim,
It might simply be that, because of multipath reflections, there is a
'notch' in part of the spectrum of TV signals. This is best seen using a
spectrum analyser, which shows the levels of all the signals at the same
time. Moving the aerial slightly (up or down, side to side, forward and
back) might move the frequency of the notch to where it does no harm.

When putting up an aerial, it is good practice to check that all signals
are being received at relatively similar strengths (assuming similar
transmit powers). If one or more signal is unaccountably lower than the
rest, 'wave the aerial around' a bit (if you get what I mean) to try and
bring up the weak signal, even if this entails losing a bit of level on
some of the stronger signals. I bet that this wasn't done when you
aerial was put up.

Ian.

Wasn't that (IIRC) how Rod Hull met his end ?

Indeed. In their account of his demise, the Sun newspaper helpfully included
a diagram of his roof, with a dotted line indicating his final trajectory,
alongside a photograph of "Emu in his prime".

Dunno if it matters, a sensitive box is more sensitive too noise,
Swings and roundabouts.......

Do you suffer from pixellation/loss of signal in rainy conditions? If not,
then there's nothing to worry about. I have a line-of-sight to Sutton and
have a signal level of 25% on ch55, but the data quality is at 80%. It's the
SNR which is the key factor.
