10. REFERENCE 10-1-2. Mobile (1) Antenna Use a sturdy mount for the mobile antenna since HF antennas are larger (and have more wind load) and are heavier than VHF antennas. A bumper mount is recom- mended for general use. The ground side of the mount must be well grounded to the car body, since the body itself functions as the ground plane for the [...]

--J The antenna to be used should first be checked with a dip meter to insure that it is designed for your oper- ating band, then the impedance matching should be checked with an SWR meter. (Fig. 10-3) The VSWR should preferably be less than 1.5: 1 for stisfactory operation. For antenna adjustment refer to the antenna instruction manual. (4) Antenn[...]

10-2-2. Noise reduction In motor vehicles, noise is generated by the ignition system. Other sources of noise include the wiper and heater motors. Although the transceiver is equipped with a noise blanker to minimize ignition noise, it is imperative that some preventiye measures be taken to reduce the noise to the lowest possible level.
