I've seen a few of these over the past few years.
LNBF's that do C and Ku Band, and Linear (H/V) Circular (L/R) Polorization.
But because they still needed the Dielectric plate for switching linear plarisation to circular polarisation have bad reports on one side of the reception (K-Band or C-Band). [Anybody seen any electrical Linear/Circular switching ones?]
But this is usually because most Ku-Band signals are Linear H/V - which I think only 36°E has Circular L/R reception from NW Europe, UK reception area.
And a lot of C-Band signals are Circular L/R in the same reception area.
So leaving the plate in gives normal C-Band L/R reception, but weakened Ku-Band H/V reception and without the plate gives poor C-Band L/R reception, but normal Ku-Band H/V reception.
I still think it sounds like a sound idea to help alignment on smaller dishes (using weaker Ku-Band H/V reception to peak the dish for C-Band L/R reception).
Anybody out there had success? And with which model/s? (as some are rebranded)
I intend to give this a go, as my C-Band dish has definately moved in the high gale force winds we had the last two years (Winter 2018/9 and 2019/20). And with C-Band now leaving 5°W with it now being in inclined orbit. I only have stable reception from a few channels at 40°E, 20°E, 10°E at the moment, with occasional signal catches from 2.9°E, 3.1°E & 5°E at the moment.
