highest freq. BNC is good for?	Reply

How high of a frequency are BNC connectors good for with out loss. I would guess UHF is fine but are they good enough for 900mhz or does one need something like mini-uhf that motorola uses?

A real (mil spec type UG-88) BNC is constant impedance and virtually lossless to at least 3 GHz; the TNC (threaded version) to >6 GHz. Used in microwave labs all over the world well into the SHF region (3000 MHz+). WB2WIK/6

Amphenol RF states: Amphenol 50 ohm BNC connectors are miniature, lightweight units designed to operate up to 11 GHz and typically yield low reflection through 4 GHz. [so you should be good on 33, 23 & 13 cm, even 9 cm] See: http://www.amphenolrf.com/products/bnc.asp?N=0&sid=482637007548E17F&
