RF Microwave Pyramidal Antenna test Absorber

Broadband Polypropylene RF Microwave Absorber

DMC-PP-MI series are high performance Polypropylene RF Microwave absorber covering wide band frequency range. The appearance and characteristics are similar to HY series, but PP-MI series has been specifically designed for best performance at Microwave frequency range. Therefore, this PP-MI series of absorbers are highly preferred for Antenna Pattern Measurement (APM), Compact Antenna Test Range (CATR), Radar Cross Section (RCS) and Electronic Warfare Test (EWT) application.
