Nokia Siemens 471443A.103 – WMHD dual mast head amplifier (MHA), WCDMA 2.1GHz, AISG-controlled. Tech-Star (UK-based, shipped worldwide).

The Nokia Siemens 471443A.103 is a WMHD dual mast head amplifier (MHA) for WCDMA 2.1 GHz networks, controlled via the AISG (Antenna Interface Standards Group) interface. Mast head amplifiers are mounted close to the antenna at the top of the tower or pole, ahead of the feeder cable run, and provide low-noise amplification of the received uplink signal before it travels down to the base station. This reduces feeder cable losses and improves receiver sensitivity, extending cell coverage and capacity. As an AISG-controlled unit, it can be remotely monitored and adjusted from the base station or network management system alongside other antenna line devices such as RET controllers. Units of this type are commonly sourced for tower-top RF chain maintenance, replacement and network optimisation projects on existing WCDMA 2.1 GHz sites. Tech-Star (UK-based, shipped worldwide) supplies tested tower-mounted RF hardware. Get in touch with our team to confirm compatibility and current stock.
