AM 9144 – Modular Antenna Mast

The double telescopic antenna mast / tripod is continuously height-adjustable. The mast rods are made of glass fibre to avoid unwanted reflexions. The modular design makes it possible to use different telescope parts and it can be mounted on a mast foot made of stainless steel or one made out of low-reflective fiberglass. Both of them provide a secure stand and easy adjustment on uneven ground. Antennas or adapters can be mounted on the 3/8″ male thread.

Overall height adjustmeint: (depending on configuration)	0.56 m – 3 m
Antenna or adapter mount:	3/8″ (male)
Material mast:	GFK / fibre glass
Diameter of circle around foot:	aprrox. 1.5 m
Weight: (depending on configuration)	5 ~ 7 kg

Mast Adapter

Antennas can be mounted directly to the 3/8″ thread of the telescopic part or can be attached using the mast adapters (like shown above). These adapters provide flexible mounting options to suit various installation needs. For more detailed information on specifications, compatibility, and installation guidelines, please refer to the respective data sheets for each adapter.

Telescope

The modular telescopic parts are interchangeable. So different height adjustments can be realized. When selecting the telescope, please make sure that an additional vertical offset may be caused by the mast foot and the optional wheels.

Mast Foot

AM 9144 M-VA

The mast made of stainless steel fits for all AM 9144 T – models. With its adjustment screws strongly uneven ground can be compensated. A rotating star can lock the legs.

AM 9144 M-GFK

The low-reflection mast foot made of fiberglass is suitable for all AM 9144 T models. With its adjustable rubber feet slightly uneven ground can be compensated. Due to the simple plug-in system the mast foot set up is quick and easy.

AM 9144 M-TILT

The tiltable mast is suitable for all AM 9144 T – models. With the hand wheel, the entire mast can be tilted. This is necessary as otherwise a polarization change of the antenna, due to the antenna elements, would not be possible.

With its adjustment screws strongly uneven ground can be compensated. A rotating star can lock the legs.

AM 9144 M-FIX

The mast foot made of zinc-plated steel fits for all AM 9144 Telescope elements, e.g. AM 9144 T-12.

Designed for rigid attachment to the floor by three M8 Cross-handle screws, the required threaded hole length is 30 mm.

Wheels

AM 9144 W-VA

The wheels are suitable for the stainless steel mast foot AM 9144 M-VA. They are simply attached instead of the end caps into the legs and are locked with the star handle screw. With the parking brake, the mast remains in position.

AM 9144 W-GFK

These wheels are suitable for the GFK mast foot AM 9144 M-GFK. The wheels are simply assembled instead of the rubber feet. With the parking brake, the mast remains in position.

Extender

The Extender is screwed by its 3/8″ female threads on top of the telescopic part and extends it. The length of the extender is made in a way so that a stepless height adjustment remains possible. The resulting height of a retracted telescope with extender corresponds to the height of a completely extended telescope.

Overall height adjustment in different configurations

When using an extender, the height adjustment range is increased depending on the length. This should be considered when calculating the total height adjustment range.
