Title: RF TRANSFER Switches ("baseball" switches) -- update Post by: WBear2GCR on December 19, 2019, 01:48:24 PM Recently I acquired a number of these.
Don't need that many. So several are for sale. These are TRANSFER switches, which can be used as a T/R relay, but have a different switching pattern than say a DPDT switch. Please look it up, if ur not familiar with them? These are Sector Microwave Industries SM7N. 3 available with type N SOLD 2 BNC, and 1 SMA. $30ea for any of the remaining swithces Each $40 + $8.00USPS flat rate box. Continental USA only, please. The picture is a stock image - the actual units are used, clean. I took one apart to see how they do it... that pic is mine. Also have a typical derating chart from a different mfr - keep in mind the published rating is usually at GHz, not HF. Hot switching is not recommended (for any TR switch).

Can get transported to Marlboro Hamfest, if requested. _-_- |
