Man, that's some beefy conventional coax. It's a 50 ohm cable.The center conductor is .195", with two silver plated shields.Attenuation is 2.5 db per 100', compared to 5.0 db 100' for RG-214 and 1.42db per 100' for 1/2" Heliax hardline. It's a high power cable designed for RF voltages up to 11,000 and I'll hazard the guess that a typical application would be high power radar systems. Nothing wrong with this stuff but where you might run into difficulty is scrounging connectors for it without paying an arm and a leg. The male connector is a UG204/CU or UG204/DU. Long runs of this stuff used in an environment subject to wide temperature variations should use a captive contact connector which is available from Kings Connector, part no. KN59-177. It may end up being more cost effective to sell the stuff for scrap and buy 1/2" hardline and connectors with the proceeds. In a message dated 6/18/2007 8:46:37 A.M.

Hi- Kind of off subject- our group was given a bunch of RG177U,Looks to be heavy duty coax. Would anyone know impedance ,and if it can be used for repeater usage? Tks,Jerry ************************************** See what's free at http://www.aol.com.
