Installation and Start-Up Quarter Length Whip Antenna Shorter Length Whip Antenna Installing An Antenna Be sure the antenna is properly connected to the radio before transmitting. Prolonged transmitting without an antenna, or use of a poorly matched antenna, could cause damage to the CB. For the most reliable operation and maximum range, Cobra recommends using a vertically polarized, quarter wavelength whip antenna. Shorter, loaded-type whips are adequate when maximum range is not required. NOTE: Mobile installations (cars, trucks, boats, etc) should be made only with a non-directional antenna system. • A standard antenna connector (Type SO-239) is provided on the black box for easy connection to a standard PL-259 cable termination. • Cobra antenna models are recommended; order directly from Cobra at www.cobra.com or contact your local Cobra dealer. • For maximum efficiency in boat installations, a ground plane is required, unless the vessel has a steel hull. Consult your CB dealer for information regarding an adequate grounding system. Installing an External Speaker 1. Mount external speaker in desired location. 2. Plug into the back of the CB transceiver. The external speaker should have 4-8 Ohms impedance and be able to handle at least 4 Watts. NOTE: The external speaker is a Bridge Tied Load (BTL) design. Do not short the speaker wires to ground as it may damage the speaker amplifier. 6 Operation Display A B C DE F DX NB/ANL VOX AMLNK G AQ RX H WX!
