4.5cm broad band C/X secondary focus receiver (4000-9300 MHz)

This is a broad-band receiver with two linear polarizations. The system is still under test, but could be used on a "shared-risk" basis.

normalized Gain curve (G = A0 + A1·Elv + A2·Elv2)			Observed in	confirmed
A0 = 0.9928	A1 = 4.212E-4	A2 = -6.158E-6	Jun 2016

Comments:

The gain curve was corrected for opacity (though it is small, < 0.02 throughout the band).
