Active antenna multicouplers
A family of active Rx multicouplers of advanced design which utilizes up-to-date LNA technologies and new generation magnetic components to provide high-level
performance over an extended frequency range and other favorable characteristics as low-ripple insertion loss, low noise figure and high amplification linearity.
The active multicouplers allow coupling of several radio receivers to a single antenna over the 20kHz to 32MHz frequency range without reduction of the signal level, as the antenna signal is amplified before distribution to ensure a 0dB
nominal loss between the antenna input and each receiver.
Active antenna
multicoupler MR-2-8, 8+8 outputs The MR-2x8/A allows
coupling of 8+8 radio receivers to two Rx antennas over the 20kHz to 32MHz frequency bands, with capabilities for extension to 16 outputs by addition
of a power divider and a circuit card
Designed to meet a specific Customer requirement, the MR-2x8/A is composed of two identical and independent standard MR-1x8 multicoupler units ( one antenna
input and 8 receiver outputs), assembled in a 19” Rack Standard 1U configuration.

Active antenna multicoupler
MR1-16A, 16 outputs The MR 1-16 A Multicoupler is a new addition to
the line of antenna multicouplers developed by Ro.Ma. enginery for association with radiocommunication systems in operating
environments where space for antenna installations is at a premium. The MR 1-16 allows coupling of 16 radio receivers to a single antenna over the 20kHz to 32MHz frequency range without reduction of the signal level, as the antenna signal is
amplified before distribution to ensure a 0dB nominal loss between the antenna input and each receiver.
