MZG-Mount - Datasheet

Description

Heavy-duty magnetic mount with thread stud for “ZG”-type antenna whips.
Provided with FME connecting system (FME-cable must be ordered separately).
Can be used at: 27 – 400 MHz using standard whips
and at: 400 – 470 MHz using specially accommodated whips.
Extraordinarily high attaching power: takes up to 1.6 m long whips.
Silicone layer on contact surface protects the car roof and ensures maximum friction.

Typical Response Curve

USING THE MZG-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 MZG-Mount 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 MZG-Mount ensures low wind load.A silicone layer applied to the whole contact surface protects the car roof and ensures maximum friction. The MZG-Mount is provided with a M8 x 1 thread mount system fitting the Procom “ZG”-type antenna whips.

INSTALLATION

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

TUNING
Below 400 MHz	Use the cutting diagram for the corresponding ZG-mount model using the same type of whip as a guidewhile 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.

Generally:Order this magnetic base by simply asking for MZG-Mount. (FME-cable and FME-connector are ordered separately).

27–400 MHz

The whip and the MZG-Mount are ordered separately. All whips available in normal ZG-mount version also fit the MZG-Mount. Whips are tuned with an SWR-meter using the ZG-version cutting diagrams as a guide.

Complete antennas within

400–470 MHz

The whip and the MZG-Mount are ordered together by coding MZG-Mount into the antenna designation as e.g. MU 4-MZG/h. Please consult the ZG-mount leaflet for the particular whip type in question to check if the whip is available with MZG-Mount.
