Dave, There's nothing special about a fuse to protect test equipment from accidental application of RF. My General Dynamics (Motorola) R2600D uses 1/16 ampere axial fuses behind the antenna and generate BNC connectors, and these are easily replaceable from the front in less than a minute. (Yeah, I made a boo-boo with a mobile radio hooked up wrong, but the fuse did its job and protected the instrument.)
I don't know who makes these special connectors, but perhaps you could buy them from GD or Aeroflex and retrofit them to your own equipment. The connectors are designed so that the 50 ohm impedance is maintained when the fuse is in place. The fuses are about the size of a grain of rice. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Dave Sent: Saturday, March 20, 2010 3:37 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] RF Fuses Any ideas where I can buy RF fuses, either the actual fuse element or the combination holder/fuse say in a BNC configuration, to portect the input of a spectrum analyzer or service monitor?
