The antenna should initially be adjusted with a dip meter tehen impedance matching be checked with an SWR meter See Fig 4 19 Preferably SWR should be less than 2 1 for satisfactory operation Refer to the antenna instruction manual for the manufacturers tuning recommendations NOISE REDUCTION In motor vehicles ignition noise is generated by t e ignition coil or distributor Other sources of noise include the wiper or heater motors Although the TS 830M is equipped with a noise banker to minimize ignition noise it is imperative that some preventive measures be taken to reduce the noise to the lowest possi ble level 1 Antenna Location Selection Since ignition noise is generated by the vehicles engine the antenna must be installed as far from the engine as possible 2 Antenna Matching In general mobile antennas have a lower impedance than 50ohm coaxial cable resulting in a mismatch between the antenna and the coax Such trouble can be eliminated by using an antenna tuner OUTPUT INPUT OUTPUT INPUT Fig 4 20 Antenna Matching Circuits 3 Bonding The component parts of motor vehicles such as the engine transmission muffler system accelerator etc are coupled to one another at DC and low frequencies but are isolated at high frequencies By connecting these parts using heavy braided ground straps ignition noise can be reduced This connection is called bonding 4 Use Ignition Suppressor Cable
