That looks a useful type of clamp from the neewer range of products. Is it part of a tripod assembly or a standalone item?

Maybe someone can confirm if this seems likely, but I have gained my missing 2db by replacing the O Ring in my C120 LNB - I thought they were just to keep water out but perhaps keep the signal in too?

A little less analogue, and a lot more crap.

You may have removed some humidity in the feed during the dismantling.

Well the hard labour is almost done, I just have to reassemble the other Raven now it's in its new home.. then the wiring begins.. But it looks wet all weekend so doubtful we'll be done this week :(

Aye, proper good kit, not a DiSEqC motor in sight as far as eye could see ?
Thanks all!

Just one, hiding at the front on the 1.2m Gibby, Only 3 motorised dishes to be fair. Rest are fixed.

Was going to motorise the 2nd 1.2m Gibby I have but decided to just fix it on 7e instead, 3 is plenty.

Keep it hidden, it will spoil the appearance of a nice landscape.

Been spending a while finalising the two Ravens, I have got them as good as they'll be and have some interesting results between the RX Feed Arms model and the TX/RX heavy duty arms:

Scan of 16e on both 2 minutes apart, currently raining but OK for a comparison, showing about a 1-1.5db difference towards the TX/RX arms. Some freq comparisons are a bit higher than others which makes me wonder if I need to tweak the LNB skew a bit on one of them.

The arms themselves 'shouldn't' make a difference of course, but unless you have LNBs with identical characteristics and there are no differences in the reception a couple of metres apart, you might be looking at subtle reflector imperfections, though again there shouldn't be. Try running a metal detector across the whole surface to verify the mesh runs right to the edges.

Even assemblers at the factory can have a bad day.
