Here is a chance for you fellas on a budget to get quality SMA relays cheap!  I have a lot of relays I have removed from military test sets and various equipment, and the junkbox is just overflowing. These are all 28 VDC coil, failsafe style, SMA (F), rated DC-18 GHz, made by Amphenol, RLC, M/A-COM, dB Products, etc., all good stuff!  Nice relays, label may be scuffed but who cares about the label if you are hiding these in a box at the top of the tower anyway!  Several are shown but sold one at a time, I have lots to sell, so picture is sort of representative, if you want a particular one, ask.  Remember I combine items to save shipping so ask for total on multiples, before you pay!
