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.

Datasheet AM 9144

 Specifications:  
 Overall height adjustmeint: 0.56 m – 3 m
 (depending on configuration)
 Antenna or adapter mount: 3/8″ (male)
 Material mast: GFK / fibre glass
 Diameter of circle around foot: aprrox. 1.5 m
 Weight: 5 ~ 7 kg
 (depending on configuration)
  1. Mast Adapter: Suitable for adapters with 3/8” female thread. AA 9202, AA9202 POM, AA 9203, PDG 9211, RA 9215, AA 9205, AA 9209, KG 9201
  2. Telescope: Interchangeable telescopic part in different sizes.
  3. Mast Foot: Available in 3 different versions: Stainless steel, GF or tiltable mast foot
  4. Wheels: These wheels are optionally available. Depending on the foot, they have a different mounting-system.
  5. 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.

Overall height adjustment in different configurations
Mast Foot Wheels Telescope
AM 9144 T-05 AM 9144 T-08  AM 9144 T-09 AM 9144 T-12

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.

]]> Biconical Antennas have dipole like characteristics (e.g. circular directional pattern in the H-plane,”8″-shaped in the E-plane, fixed phase center, comparable gain), with an enormous wide bandwidth achieved by the double cone elements. One of the earliest and worldwide most popular biconical antenna designs is the BBA 9106 with balun VHA 9103 B. During the last years a growing need for expanded frequency ranges arised, which led to the design of biconical antennas reaching down to frequencies of 20 MHz and up to 18 GHz and above. A further increase of bandwidth was achieved with qualified 4:1 baluns, providing a typical gain increase of approx. 6 dB at the lower frequency range. The biconical elements can be mounted and dismounted within a few seconds providing perfect contact repeatability thanks to special clamping fixtures. A small wrench made of insulating material is supplied with the balun, it is tied to the balun head and thus always available whenever needed. Biconical antennas can be used for many applications, in which half-wave dipoles have been used traditionally. An enormous reduction of measurement time can be achieved, because the time consuming tuning of the antenna elements to the half wavelength is not needed, an important condition for sweeped broadband measurements. In typical dipole applications several discrete frequencies are measured, in contrast the biconical antenna allows continuous sweeps, where site anomalies are discovered much easier.

Overview Biconical Antennas
Collapsible or Open Conical Elements

Typical applications for biconical antennas are:
Broadband RX-antenna for emission testing (20-300 MHz)
TX-antenna for immunity testing, especially at low frequencies
Measurements of shielding effectiveness
Evaluation of test sites e.g. anechoic rooms (FAC) and open area test sites (OATS)
Passive field probe for immunity testing

A big variety of baluns and biconical elements allows to choose the optimum antenna for each specific application. The baluns marked with “RX” are especially designed for receiving applications (because of their superior symmetry), the baluns marked with “TX” are suitable for immunity testing with high power.

Tuned half-wave dipoles have been among the most important antennas from the beginning of rf-technique. The characteristics of half-wave dipoles have been calculable very early using the Maxwell and Hertz equations. Therefore the half wave dipole became a reference antenna. The ideal (lossless) half-wave dipole has an isotropic gain of 2.15 dBi and an impedance of 73 Ohm. The directional pattern is circular in the H-plane, “8-shaped” in the E-plane with the maxima perpendicular on the dipole axis.
The half-power beamwidth (-3 dB) is approx. 78°. The impedance of real dipoles is depending on the thickness/length ratio of its elements, typical values are 60-70 Ohm.
Dipoles for industrial applications are available in the frequency range from 30 MHz to up to approx. 4 GHz. The dipole elements are length variable (telescopic) or with fixed length, the latter especially above 1 GHz. The most important applications are test site evaluations (NSA, normalized site attenuation) and the determination of ERP (Effective Radiated Power) respectively EIRP (Effective Isotropic Radiated Power).
