Antennas CB Antenna Note For optimum performance in passenger cars the ideal antenna location is on the center of the roof. Second choice is on the center of the trunk. Note Because many newer trucks feature fiberglass door skins, the outside mirror must be grounded to the chassis via a ground strap when antenna is mounted on the mirror bracket. Note 3-way Combination Antennas are also available which allow operation of all three bands (AM-FM & CB), using a single antenna. However, this type of antenna usually results in less than normal transmit and receive range when compared to a standard-type "Single Band" CB antenna. Contact your local dealer for further information. CB Antenna Since the maximum allowable power output of the transmitter is limited by the FCC and IC, the antenna is critical in affecting transmission distance. Only a properly matched antenna system will allow maximum power output*. Cobra loaded type antenna models are highly recommended for most installations. Consult your Cobra dealer for further details. 1 A standard antenna connector is provided on the transceiver for easy connection. *Under Industry Canada regulations, this radio transmiter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Safety notice: The device complies with the MPE requirements by providing a safe separation distance of 14.2 in (36 cm) between the antenna, including any radiating structure, and any persons when normally operated . This is based on a typical installation and an antenna with 3 dBi of gain. This device is approved with emissions having a source-based time-averaging duty factor not exceeding 50%. Marine Installation Ignition Noise Interference Marine Installation The transceiver will not operate at maximum efficiency in a boat without a ground plate, (unless it has a steel hull). Before attempting installation , consult your dealer for information regarding an adequate grounding system and prevention of electrolysis between fittings in the hull and water. Iginition Noise Interference The transceiver will not operate at maximuUse of a mobile receiver at low signal levels is normally limited by the presence of electrical noise. The primary source of noise in automobiles is from the alternator and ignition system. Typically, when signal level is adequate, the background noise does not present a serious problem. Also, when extremely low level signals are being received, the transceiver may be operated with the vehicle's engine turned off. The unit requires very little current and therefore will not significantly discharge the vehicle's battery. Even though the Cobra 29 LTD Classic has an automatic noise limiter, in some installations ignition interference may be high enough to make good communications impossible. Many possibilities exist and variations between vehicles require different solutions. Consult your COBRA dealer or a 2-way radio technician for help in locating the source of a severe noise. 6 7
