29LTDC_CLASSC_MANL_ENG.qx_29LTDDEJR_manual.qx 11/5/13 3:17 PM Page 6 Marine Installation Ignition Noise Interference Antennas 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.

This calibration is critical in order to achieve optimum performance. Note Calibration must be made in an open area (never in a garage). Vehicle doors must be closed.
