The information below will help you derive the best performance possible from the ATAS 100 120 Active Tuning Antenna System Grounding It is critically important that you establish a good mechanical and RF ground connection for your ATAS 100 120 as with all vertical antennas Mobile mounts which are bolted through the vehicle s roof or otherwise mechanically affixed will usually be satisfactory However magnetic mounts do not provide the RF grounding necessary for good performance and are not recommended for use with this antenna Tuning Procedure The feedpoint impedance of the ATAS 100 120 resistance and reactance will necessarily vary over a wide range when you change bands Occasionally the transceiver s micropro cessor will not initially be able to determine the proper direction for the ATAS 100 120 to travel inward or outward for best SWR To resolve this situation the transceiver will then command the ATAS 100 120 to retract fully to its minimum or maxmum height and thence restart the tuning process In this in stance the WAIT icon will remain on the display after you press the A TUNE key If this happens do not press the A TUNE key repeatedly The transceiver will remain in the receive mode as it retracts this may take up to one minute Thereafter the transmitter will be engaged and the ATAS 100 120 will be automatically adjusted for best SWR The TUNE icon will then disappear from the LCD
