21-Inch 82-Channel Omnidirectional TV Antenna w/Fixed FM Trap (88-108 MHz) (150-1624) Preparation Faxback Doc. # 32726 IMPORTANT ANTENNA NOTES This antenna system is designed to work properly when the power injector is connected to the antenna through only 75-ohm coax cable. The power injector has an indicator light to indicate that: DC power is supplied to the antenna There are no shorts in the connection between the power injector and antenna The coax cable between the power injector and the antenna is used for: Carrying DC power from the power injector to the amplifier board in the antenna Carrying the amplified TV signal from the antenna, through the power injector, to the video equipment If any devices are used in your home cabling system (such as amplifiers, splitters, combiners, matching transformers, or 300-ohm cable), they must be connected only between the power injector and your video equipment. Any devices connected between the power injector and the antenna might cause a short in the amplifier power source. If this happens, the injector's indicator does not light and the signals to your video equipment (multiple TVs or VCRs) might be significantly degraded. Pre-Installation Test To make sure your antenna system works properly before installing it, perform this test. 1. Connect a temporary 75-ohm cable between the power injector's ANT 75 Ohm jack and the antenna's F-connector. NOTE: If installing new lead-in cable, use the actual cable to be used in the installation. 2. Connect the power injector's TV cable to your TV's VHF/UHF 75-Ohm F connector. 3. Insert the supplied AC adapter's small plug into the DC 12V jack on the power injector. NOTE: If installing the antenna in a motor home, we recommend you use a DC cord (such as Cat. No. 273-1533, not supplied). 4. Plug the supplied AC adapter into a standard AC outlet. If the power injector's indicator lights, the antenna is properly connected. (WL/EB 2/26/96)
