42-33-01 Series, 118-174 MHz, Receiver Multicouplers provide unequalled performance in a 1-rack unit (1-3/4 inch) space-saving package. The high performance LNA ’s exhibit a very low noise figure while providing a (100% measured) 3rd order output intercept point in excess of +40 dBm. The multicouplers are designed with a minimum excess gain of 10 dB which gives maximum sensitivity in rural applications. All the units are designed for ease of expansion, with no change in system gain in most cases. Two basic models cover the most popular applications from 118 - 512 MHz.

Consult our comprehensive RF component and accessories catalog for Receiver Multicoupler Systems components such as LNA’s and power dividers for special needs you may have. All TX RX receiver Multicouplers are easily expandable by either adding additional power dividers to the existing chassis or by addition of a 1-rack unit deck. The 16-channel BNC models have 2 terminated BNC connectors for non-invasive expansion of up to 16 additional outputs in 8-output blocks, with no change in performance or specifications. All necessary cables with attached connectors are included in each kit.

  • Space-saving, 19” 1 RU rack mount design
  • Designed and manufactured high-performance LNA
  • Auto-Ranging AC Power, 85-264 VAC 50/60 Hz / 22-30 VDC
