TIA568 Wiring Standards

How to decide which wiring pattern to use:

1. Does the job specification call out a wiring pattern?
2. Does the customer/end user have a preference for T568A or T568B?
3. Have patch panels already been purchased for the job? If so, they will probably be either T568A or T568B. The jacks should be wired to the same pattern as the panels.
4. Are you adding on to an existing wiring plant? If so, your new wiring should match the existing wiring.

If none of the factors above apply, either T568A or T568B may be used. It is important to ensure that the workstation connectors and the patch panels are wired to the same pattern. T568B is commonly used in commercial installations, while T568A is prevalent in residential installations.

Features 75 ohm input for convenience and easier installation. Universal housing can be used with any off-air TV antenna. Made of high impact ABS material, mast mounted for easy installation. Flexible polyethylene boot covers on 75 ohm models keep connections clean, dry, weather-protected. Zinc-plated steel hardware; all mounting hardware included.

Selectable FM trap reduces FM signals (88-108 MHz) -15 dB to prevent overload, tunable FM trap reduces a 3 MHz band width by -12 dB. Both adjustable - switchable without opening the housing.

Transistor burn-out virtually eliminated with specialized circuitry featuring fast recovery diode that protects against lightning-caused pulses. Operating temperatures -40° to +140° F. 117 VAC UL and CSA approved power supply is included. (Does not include F-connectors.)

U.S. Patent No. D335,887, D358,365, 5,515,240 (Power supply housing design)

NOTE: Preamplifiers and/or amplifiers only amplify the signal your antenna receives. They cannot extend the receiving range of an antenna or help pull in signal. Also, DO NOT use the higher gain models within 35 miles of your transmitters.
