Dual Band Glass-Mount Antenna (190-0324) Installation Faxback Doc. # 18987 MOUNTING THE ANTENNA Before you mount the antenna, move your vehicle to a shaded location where the temperature is between 70 and 100 (degrees) F. If the vehicle's glass is too hot or too cold, the antenna's adhesive might not properly set. 1. Select a location for the antenna. Typical mounting locations are the top center of the front or rear windows. Be sure the location you select: Does not block the driver's view Does not interfere with windshield wiper operation Is not coated with a metal film-type sunscreen Is not on a defroster element Important: Do not remove the paper backing from the coupler box or antenna base until Step 4. Once you stick the coupler box or antenna base to the glass, you cannot remove it without damaging it. 2. Position both the antenna and the coupler box at the desired locations to confirm that neither will interfere with your vehicle's normal operation. NOTE: Position the coupler box with the coax connector facing to either side. 3. Use the supplied alcohol wipe to clean the glass at the mounting locations. Allow the glass to dry completely before continuing. 4. Remove the paper backing from the coupler box and carefully position it over the mounting location. Then firmly press it into place and hold it for 5 seconds. 5. Remove the paper backing from the antenna base and carefully position it over the coupler box. Then firmly press it into place and hold it for 5 seconds. 6. For 70 cm operation, clip the radial over the coupler - box's connector. Make sure the redial is parallel to, and at least 1/2 inch from, the edge of the glass. 7. Screw the supplied cable's connector onto the coupler box. 8. Route the cable to your transceiver and connect it according to the transceiver's instructions. 9. Loosen the antenna base's hex bolt with the supplied allen wrench, and position the antenna so it is straight up and down to tighten the hex bolt. TUNING THE ANTENNA For the best performance, tune the antenna using an SWR meter. Follow the SWR meter's instructions to connect it to your transceiver and the antenna cable. To adjust the SWR, turn the tuning capacitor in the coupler box using the supplied plastic tuning tool. NOTE: A very small change in the tuning capacitor's setting can make a big difference in SWR. Tune the antenna in very small increments. (br/all-02/14/96)
