LNB is it worth changing

[frundlemud]

My Inverto LNB rt is at least 10 years old not sure of the model but it is quite a long item see photo.
my question is would I see any improvement if I purchased a new one and if so what model.
Triax 1.1 30w to 39e motorised. Zgemma H2s.

Shrewsbury town supporter so be sympathetic.

Did you ever experiment with sliding that LNB in and out to get the best focal point.

Inverto Black Ultra LNB's get a good reputation on your dish as do the Golden Media range of LNB's.

Gains will be small and possible better on one band and not so much on another, there is no miracle LNB .

Yes I did and still do sometimes. I moved it a few minutes ago to try to read the label but it is badly defaced. Quite easy to adjust as LNB is
only 1.4 above patio dish on pole tripod legs bolted to heavy old concrete slabs but still adjustable for plumb.
