Installation Instruction - SW3-707 Part Number: MUG-NMO The MUG-NMO is a UHF ½ wave antenna to fit on a NMO type base. The antenna is available in different versions, pre-tuned for a specific frequency range. The default tuning mode is for mounting on a non-conductive (e.g. plastic) panel. Mounting Environment B. The antenna is supplied tuned for installation on a non-metallic panel. (see section D for tuning requirement if used on a metal panel). The antenna should be located as far as possible from existing metal structures and on a flat, level surface to provide an effective seal to mounting the panel. The antenna location should be able to maintain safe minimum distance as shown in Section G. Fitting the Antenna C. The NMO panel mount base should already have been installed according to the manufacturer’s instructions. Ensuring that the sealing gasket is properly located on the antenna base, screw the antenna onto the NMO base thread and firmly hand tighten. ! Introduction A. Care for the Antenna E. If removing the antenna for a carwash, a protective waterproof cap should be fitted to the base. Ensure that the antenna is re-fitted before attempting to transmit. Check the antenna periodically and re-tighten if necessary. Important Safety Notice F. To ensure that human exposure to radio frequency energy is within safety guidelines, transmit only when people outside the vehicle are at least the minimum distance away from installed antenna. NOTE: The distance depends on the transmitter power. Transmitter Power Output Min. Distance From Antenna 7-15 Watts 1 ft (31cm) 16-50 Watts 2 ft (62 cm) Over 50 Watts 3 ft (93 cm) SW3-707 - www.panorama-antennas.com MUG-NMO - SW3-707- Document Version 1.0 Testing & Tuning the Antenna (If Required) D. A DC check should be carried out on the NMO base, to check for low resistance earth continuity: There should be a low resistance between the connector body and vehicle chassis, value <0,2Ω An antenna analyser or VSWR meter will be required to check the antenna tuning. If the antenna is fitted on a non- conductive panel, no tuning should be required but a VSWR check should be carried out. With the antenna fitted on a metallic panel, it may be necessary to re-tune the antenna, which can be determined with a VSWR check. To adjust the tuning, remove the rod using the supplied hex key, remove a small amount from the lower end, refit the rod and check the VSWR. Connect the antenna to the wireless device and carry out an “on air” check if possible. IMPORTANT: DO NOT TOUCH OR ADJUST THE ANTENNA WHILE TRANSMITTING all-guides com
