From what I can find, the connector was originally developed for the German Military, which needed a rugged, efficient connector that was easy to install properly.<\/p>\n\n\n\n
This style of connector is very popular with cellular antenna manufacturers due to its relatively high power handling capability and excellent passive intermodulation performance.<\/p>\n\n\n\n
According to Amphenol, their 7\/16 DIN connectors have the power handling capability of 3000 watts\/1 GHz @ 25C (77F). That is a fairly low temperature. They give the working voltage as 500 V RMS continuous, which is 5000 watts at 50 ohms impedance. That, of course, assumes a 1:1 match, which is never the case. The connector is probably safe to ~2 KW in normal operating conditions for VHF and UHF TV operation.<\/p>\n\n\n\n Also, keep in mind that RG-8, RG-213, RG-214, LMR-400, and Belden 9913 look similar but they use different connectors because the inner conductor of the latter two is larger than RG-8, RG-213, or RG-214. This happened on a project recently. It came time to crimp the pin on the center conductor and, oh no! The pin was too small!<\/p>\n\n\n\n A properly installed connector will be outdoor water-resistant in most weather conditions. <\/p>\n","protected":false},"excerpt":{"rendered":" These connectors appear on the backs of various FM and lower-power TV transmitters.
