Technical brief

Eight-output VHF multicoupler

Double the channel count of the VHF 4-Channel Receiver Multicoupler in the same 1U chassis. OIP3 spec relaxes slightly (+25 dBm vs +33 dBm) but stays well above receiver-limit.

Solves these problems

Distributing one antenna feed across multiple receivers without sensitivity loss

A single high-quality receive antenna feeding multiple receivers — without splitting the signal level so far that sensitivity collapses, and without one receiver loading another.
