Maybe I was thinking of Farnell (who ain't so cheap). Cirkit sell them for ?2.69. Ouch! I've just found the price in the Electrospeed catalogue (?8). I got most of mine from older network installations, where people had added thinnet to (or in some places, instead of) original thick yellow ether. Older N-series tranceivers often got reused in such situations, I find. Electrospeed still claim to sell coax taps for ?22, and assorted transceiver adaptors (N-series ?15, straight single BNC ?12, dual (T) BNC ?14). -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York
