Coaxial cable was invented in 1929 and first used commercially in 1941. AT&T established its first cross-continental coaxial transmission system in 1940.[[Image:coaxialcabledata01.png]]== DS-3 ==== Common Coaxial Cable Types == === DS-3 ===== RG-6U 75 Ohm ===== RG-6U 75 Ohm ===RG6U, RG-6U. Suitable for CatTV and Satellite small dish signal from LNB. It has low loss at high frequency for cable television, satellite television and cable modems.RG6, RG6U, RG-6U. Suitable for CatTV and Satellite small dish signal from LNB. It has low loss at high frequency for cable television, satellite television and cable modems.'''Dual RG6/U Quad Shield''' (RG-6UQ) is ideal for antenna, cable television and satellite installations. Make two cable runs at one time for dual LNB satellite or satellite and antenna installations. This cable is 18AWG copper clad steel center conductor surrounded by a foam polyethylene dielectric. A bonded aluminum foil and 60% aluminum braid over another foil and 40% aluminum braid provide 100% shield coverage. This cable meets specifications for CL1, CL2, CM, CMX and CMG installations. Swept tested to 3GHz to ensure performance at applicable frequencies.RG-6UQ, RG-6QS, '''Dual RG6/U Quad Shield''' provides higher protection against radio interference, loss, and is ideal for antenna, cable television and satellite installations.
