DMH21-1 Antenna Coupler, 74.75 to 75.25 MHz, BNC Connector, 3.6 dB, <2:1, 0.25 lb

Overview

H-series antenna couplers are specifically designed to couple multiple receiver systems to a single antenna with a minimum of insertion loss. The couplers are designed to electronically split the received signals equally between the systems. In this manner, a single antenna may feed redundant systems or serve a dual-function role (e.g., glide slope and VHF omnidirectional radio range localizer (VOR/LOC)). The ruggedly built couplers are housed in aluminum cases with all circuit elements fully encapsulated. General specifications applicable to all couplers are provided in this sheet, while Table 1 indicates the recommended function of the particular type.
