Chamber Overview

The PSU ARL Anechoic Chamber, supporting antenna testing down to an attractive 100 MHz low end, is a rectangular chamber and is 100 feet long x 40 feet wide x 40 feet high.  Instrumented with a microwave receiver, heavy duty positioning equipment, and specialized antenna pattern measurement software, this facility, believed to be the largest university run chamber in the U.S., is ideal for test and development for items ranging from antennas  to integrated platforms.  The chamber supports simultaneous measurement of up to 10 antennas and has also supported optical and Radar Cross Section type tests as well as tests needing a large volume requiring high RF isolation.   A GPS repeater is available for tests requiring GPS reception.
