Belden makes an RG-59/U with copper 22 guage (7X30) center conductor and 95% coverage copper shielding for CCTV applications... the number is 9259, the attenuation (from the book) is 2.1 dB per foot at 50 MHz. Nominal impedance is 75 ohms. - Tom -- Thomas Krueger ...ihnp4!uwmcsd1!shop or University of Wisconsin Milwaukee uwmcsd1!shop@rsch.wisc.EDU Computing Services Electronics Shop 3200 N.
