The Telewave TPRD-1444C produces high performance in a compact design for the 135 – 151 MHz VHF band. These duplexers are only one-third of the size of earlier models, and deliver equivalent performance. The TPRD-1444C produces 70 dB isolation at 600 kHz, with a 350 W power rating, and insertion loss is 1.5 dB or less. The duplexer fits a standard 19 in rack, with rack height of 5.25 in.
