Before 1965 only separate battalions and regiments were allowed to wear unit crests. Now virtually every unit in the army has a Distinguished Unit Insignia (Unit Crest). Unit Crests for Non-Uniform Wear. More and more we are asked to provide miniature unit crests. These are popular as inexpensive but valued presentation items.
F connector. From Wikipedia, the free encyclopedia. The F connector is a coaxial RF connector commonly used for over the air terrestrial television, cable television and universally for satellite television and cable modems, usually with RG-6/U cable or, in older installations, with RG-59/U cable.
BUT my old Maganavox TVs (with coax input only) OK, so you are talking about RF and using F connectors. The thing about F connectors in general is that the bare center wire makes the contact, even the expensive snap-n-seal ones. So RG6 is the best to use because of the 18ga center conductor.
