[NLRS] Lens Horn Antennas

[Dr. Gerald N. Johnson, electrical engineer]

How does the gain compare to a similar sized dish? Looks low to me.
Maybe not. Based on the formula in my Standard Handbook for Electrical
Engineers a 10" dish at 24.0 Ghz and 55% efficiency would give 33.5 dBi.

Either the lens or the dish looses gain when the construction geometry
gets too far from perfect.
