The AT-220 Antenna stand is specifically designed for indoor and outdoor EMI/EMC testing facilities.
It is a sturdy tripod for antennas which can mount three of our supplied test antennas, allowing measurements to be carried out reliably and effectively.
The AT-220 antenna stand is made almost completely of resilient nylon material. The remaining parts are constructed from wood and minimal metal – this antenna tripod stand is truly built to stand the test of time.
The tripod stand is built with non-reflective materials to minimise RF reflection during testing.
Also, if you choose to purchase the AT-220 tripod we will provide you with an exclusive 3 year warranty, so there's absolutely nothing to worry about.
The AT-220 model is incredibly easy to setup and install. It stands strong and stable, with a centre rod which can extend its height from 0.6 metres to 1.2 metres. Whichever way you need to position your antenna for testing – you can rely on the AT-220 tripod to get the job done.
For mounting, the AT-220 connects to antennas with a ¼ inch x 20 bolt thread. It can handle the surprisingly heavy weight of 22.6 kg, and the weight of the tripod itself is 8.6 kg. The AT-220 is a portable antenna stand and can be easily carried from use in the indoor laboratory to the outdoor environment.
The tilt head on this model can be can be revolved 90 degrees, making it perfect for measurements requiring horizontal or vertical polarisation.
The height can be easily changed using the centre rod. Another feature is its tension adjustment mechanism which counter balances the antenna weight when the antenna is not completely centred. This really helps to minimise the 'drooping' effect.
|Antenna Type||Antenna Models||Height Range|
|Monopole Antenna||AM-741||0.8 to 1.2 meters|
|Active Loop Antenna||AL-130||0.9 to 1.2 meters|
|Horn Antenna||AH-220||1 to 1.2 meters|
The AT-220 antenna stand is versatile and can accommodate our active loop antenna, AH-220 horn antenna, and AM-741 monopole antenna.
The AM-741 Monopole antenna is the first antenna compatible with the AT-220, and can be mounted from 0.8 metres all the way up to 1.2 metres.
The AH-220 horn is the second antenna compatible with the AT-220 and can be mounted from 0.8 metres to a maximum of 1.2 metres.
The antenna tripod stand was specifically designed to be used with this AH-220 horn antenna which weighs 13.4 kg, has a height of 69 cm, a width of 94.5 cm and a diameter of 94 cm – the AH-220 is the heaviest horn antenna we currently supply – and the AT-220 tripod handles it with ease.
For mounting and supporting the AH-220 horn, the correct safety precautions and equipment should be used because of its large size and heaviness. The antenna features one mounting plate for vertical polarisation, and one mounting plate for horizontal polarisation. The middle of each plate has a 1/4-inch x 20 mounting-hole for attaching the antenna.
Finally, the AT-220 antenna stand is compatible with the AL-130 active loop antenna, which can be mounted from 1 metre to 1.2 metres.
