[NLRS] Ku-band equipment at 10.45-10.50 GHz frequencies

[John Toscano]

Does anyone want to hazard a guess (or better yet, measure performance) of
a Ku-band "universal" LNBF (rated to operate at 10.7 GHz - 12.75 GHz) if
one attempted to receive weak signals in the 10.45-10.50 GHz amateur
satellite sub-band?

I suppose the feedhorn could be milled out a bit to lower the operation
frequency just as is done with DirectTV dishes that are modified for use at
10368 MHz, although less milling would be needed due to the higher target
frequencies. But the application I have in mind would also use the LNB
electronics since it would be intended for receive-only duty. I'm thinking
it might be paired with an RTL-SDR dongle so the LO would not need to be
changed, because the dongle should receive OK at 750 MHz - 800 MHz (the
"universal" LNBF's use an LO of 9.750 GHz for the lower frequencies).

Thanks in advance.
