The ClearGain Dual Inline AWS TMA allows for mounting of the equipment to serve two RX paths in
one location on the tower, reducing time and expense in mounting the TMA. The inline feature also
allows for easier connection of the jumper cables to the antenna.

A ClearGain TMA system is modular, consisting of both a masthead unit (MHU) and a power distribution
unit (PDU), providing full compatibility with all base stations. Due to its exposed installation, the TMA
is designed to withstand demanding weather conditions and features lightning protection, fault
monitoring, and a fail-safe bypass circuitry system.
