Modular Antenna Mast – AM 9144
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.

- Telescope: Interchangeable telescopic part in different sizes.
- Mast Foot: Available in 3 different versions: Stainless steel, GF or tiltable mast foot
- Wheels: These wheels are optionally available. Depending on the foot, they have a different mounting-system.
- Extender: To increasing the maximum height of the telescopic part.
1. Mast Adapter

Antennas can be mounted directly to the 3/8″ thread of the telescopic part or can be using the adapters shown above.
For more information please refer to the respective data sheets of the adapters.
2. Telescope

The modular telescopic parts are interchangeable. So different height adjust-ments 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.
3. Mast Foot

AM 9144 M-VA
Height offset: +10 cm
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
Height offset: +5 cm
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
Height offset: +14 cm
The tiltable mast is suitable for all AM 9144 T – models. With the hand wheel, the entire mast ca be tilted.
This is necessary as otherwise a polarization change of the antenna, due to the an-tenna elements, would not be possible.
Tilt angle: > 20°
With its adjustment screws strongly uneven ground can be compensated. A rotating star can lock the legs.

AM 9144 M-FIX
Height offset: +1 cm
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.

4. Wheels

AM 9144 W-VA
Height offset: + 5 cm
The wheel 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
Height offset: + 5 cm
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.
5. 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.

wheels | 61.5 | 105 | 77.5 | 137 | 89.5 | 161 | 111 | 205 |
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.
