Re: Poor Sky reception yesterday / last night

["Tim Hawes" <timsyahoo@xxxxxxxxxxxxxx>]

Nigel,

I'm still suffering with this. Have you noticed what your signal
strength/quality is like recently and/or when you start to lose
picture? And what do the "strength" and "quality"
measures relate to?

I now think my problem is entirely tree related. With very still air I
can just get a stable picture (plenty of strength - >50%, but minimal
quality - ~5-10%) as soon as there is even a light breeze the movement
of the trees interupt the signal and the picture breaks up completely
:-(

Spending some more time looking at this over the weekend, leaving the
box off for a couple of days and changing the LNB to a spare has done
nothing to improve things.

I've now found a new spot to locate the dish which may give an
improvement. It's still close to the current position but means I'm
not pointing directly at the offending tree so I'm hoping that the
clearer sky will give me better reception.

I'm also going to get one of these LNBs. The twin is =A330-odd, the quad
is =A350-odd, but they're 0.3dB loss instead of the more usual 0.6dB.

There's a review on Satcure which seems quite positive:

I'll keep you posted with how it goes.
