Panorama Antennas MUG-NMO SW3-707 Installation Instruction

Installation Instruction - SW3-707
Part Number: MUG-NMO
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
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.
A. Introduction
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.
B. Mounting Environment
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.
C. Fitting the Antenna
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.
D. Testing & Tuning the Antenna (If Required)
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
