EMR Tower Top Receiver Multicouplers allow several receivers to share a common antenna in situations where a reduction in line loss between the antenna and multicoupler is required. These units include a preselector and amplifier within a NEMA enclosure mounted on the tower. A cable run connects the NEMA box to a power distribution panel located at the base station. The power divider provides a minimum of 23 dB of port-to-port isolation preventing signal mixing even at minimal channel separation.

Product Features:
  • Increase coverage range by reducing line loss between multicoupler and antenna.
  • NEMA-4 tower enclosure for weather and corrosion resistance.
  • All necessary wiring, hardware and cabling included.
  • 5 year standard warranty.
  • Optional upgrades include: Amplifier bypass, Stainless Steel Enclosure, Test Port (requires 2nd coaxial run up tower).
