Comtest’s MT45-Javelin Tip

The next step in polystyrene absorber technology.


At Comtest, we have long been staunch advocates of polystyrene absorbers. After all, these absorbers offer many advantages over their polyurethane foam counterparts. The only thing that held them back was their performance in microwave frequencies, but not anymore. After nearly two years of development, we are ready to introduce the new Javelin Tipped MT45-JT: a polystyrene absorber that is able to match the performance of traditional polyurethane foam absorbers while losing none of the characteristics that make polystyrene so incredibly durable and eco-friendly.


Introducing the MT45-JT

The MT45-JT owes its name to the recognizable Javelin tip it’s equipped with. This specially designed tip allows the absorber to operate in frequencies from 500 MHz all the way up to 40Ghz, meaning our polystyrene absorber now performs just as well as traditional soft foam absorbers, making it by far the best choice for use in full anechoic chambers and antenna test ranges.

Why is it the best choice?

Unlike polyurethane foam absorbers, our new MT45-JT absorbers have superior rigidity and tensile strength, they are compliant with all necessary fire retardant standards without the use of hazardous materials and they are highly resilient to humidity and changes in ambient temperature. Polystyrene absorbers are closed cell products that are certified for use in clean rooms hence they don’t leach particles and black dust. This results in an extremely durable (and virtually maintenance free) product that comes with a 25 year warranty and is expected to last well beyond that.

No downsides

What all of this means is there are no longer any downsides to using polystyrene absorbers for microwave frequency testing. Thanks to a patented design, Comtest’s new polystyrene absorbers offer performance that matches their incredible durability.

AMTA 2017

Comtest will also be presenting its new MT45-JT absorber at the 39th annual meeting and symposium of the Antenna Measurements Techniques Association in Atlanta Georgia. AMTA 2017 will be hosted at the Grand Hyatt Atlanta from October 14 to October 20. Visitors of the show are welcome to join Comtest in booth 310 for a closer look at the new absorber.
