We have LARGE QUANTITY of these excellent, very fast (4 milliseconds maximum... typically much faster!) RF relays for sale. These relays are an excellent choice for low-level RF switching, such as with the Jennings RJ1A or Kilovac HC-1 in QSK applications.

The HI-G d'Italia relays have TWO sets of SPDT contacts. One set is for RF, the other set is for auxiliary switching and control applications (non-RF). These relays are supplied as pictured in the photo, with 50 ohm RG-196A/U teflon coax and one SSMB male (snap on) and one SMB male (snap on) gold plated Mil-spec connector. These relays were removed from brand new military equipment, and are fully guaranteed!

NEW! We now have available the mating SMB and SSMB chassis mount male connectors which mate with the connectors supplied on the relays. (One of each will be needed for each relay) These are gold-plated, mil-spec connectors, removed from equipment, at $1 each! We will sell the SMB and SSMB males for this price, with or without relay purchase. In photos, the SSMB are shown on the left, SMB are shown on the right.
