DIY Antenna test ranges

The antenna test chamber is a tailormade solution and constructed using a lightweight, modular support structure suitable to install the polystyrene absorbers directly to it, like building blocks.


Do It Yourself: antenna test chamber

For the majority of microwave test applications, Comtest’s high performance polystyrene absorbers provide more than enough transfer attenuation to create a functioning chamber. RF shielding and precision gasket installation are therefore unnecessary. Because the resulting framed antenna test chamber consists of an easy to build lightweight frame and polystyrene absorber building blocks, it’s entirely possible to assemble this product yourself, making this an affordable and instructive ATR solution for schools, universities or companies on a budget.

Frame tech and absorbers

The DIY test range design approach is based on a lightweight easy-connect support system. The profiles are CNC pre-cut and individually labeled for easy handling during the assembly of the chamber. Standard mounting materials are used to connect the individual profiles. For extra stability the support frame can be mounted to the floor of the parent building. The frame technology can be applied to both small and larger antenna test ranges.

The modular design concept of our polystyrene absorbers is excellent for easy assembly, having separate baseplates and pyramids.

Chamber entrance

The doors are constructed in a very effective way resulting in the following features:

  • Low force operation.
  • Doors can be locked with a standard key-lock.
  • Absorbers can be affixed to the door leaf.
  • Both left and right sided hinges.

Up to customer preference we can include multiple entrance doors to gain easy access to antennas under test.

Easy to build

Comtest brings this innovative concept to the market as a Do-It-Yourself (DIY) building kit. The required materials are accompanied by an instruction manual and a set of drawings enabling you to build your own antenna test range.

If, however, you have doubts about assembling the range yourself, Comtest is more than willing to build the antenna test chamber for you on-site.

Shielding effectiveness

The expected shielding effectiveness of the antenna test chamber is approximately (depending on the applied absorber model):

  • 40dB at 1 GHz.
  • 60dB at 10 GHz.

Benefits of DIY antenna test chambers

Because of its robust and simple design, Comtest’s DIY chamber solution can be installed by your own facilities team for instance, using basic tools. This makes it ideal for companies with smaller budgets or teaching institutions that can use the assembly process to create an active and instructive exercise for a semester.
