ORDERING
Generally:	Order this magnetic base by simply asking for MG. (FME-cable and FME-connector are ordered separately).
Complete antennas within 27 – 400 MHz:	The whip and the MG are ordered separately. All whips available in normal Z-mount version also fit the MG. Whips are tuned with an SWR-meter using the Z-version cutting diagrams as a guide.
Complete antennas within 400 – 470 MHz:	The whip and the MG-Mount are ordered together by coding MG-Mount into the antenna designation as e.g. MU 4-MG/h. Please consult the Z-mount leaflet for the particular whip type in question to check if the whip is available with MG-Mount.

Using the MG-Mount

This magnetic mount is used to make an occasional antenna installation where it is not desirable to drill holes in the mobileunit.
A magnetic mount antenna can advantageously serve several mobile units by shifting it from one unit to another.
The MG is provided with a large-diameter, thoroughly magnetized permanent ring magnet positioned in a carefully shapedmagnetic circuit which yields an extraordinarily high attaching effect.
The further extension of the supporting surface beyondthe magnet area makes this mount stand for astounding values of bending moment and mechanical shock.
The low profile of the MG ensures low wind load.
A silicone layer applied to the whole contact surface protects the car roof and ensures maximum friction.
The magnetic mount cannot be used together with the usual wing screw normally employed when fastening mobile whips. Onthe MG the whip is mounted by means of a special “hat”-screw which together with a special fastening key is always suppliedtogether with the mount.

Curve

Installation

The magnetic mount should be mounted in the middle of the vehicle roof or rear locker to produce best omnidirectional coverage.

Tuning

TUNING
Below 400 MHz	Use the cutting diagram for the corresponding Z-mount model using the same type of whip as a guide while using an SWR-meter to tune the whip.
Above 400 MHz	Whips tuned by cutting: Use an SWR-meter. Whips tuned with disc: Adjustment diagram accompanies the antenna.
