The system consists of a master antenna and a matching transformer to match the balanced antenna with unbalanced cable and amplifiers. [5] Most antennas have an impedance of around 300 Ω. To convert it to 75 Ω, a matching transformer (or balun) is used. For trunk line isolation, a resistive inductive device known as a splitter is used. The ...
A Tower Mounted Amplifier (TMA), or Mast Head Amplifier (MHA), is a low-noise amplifier (LNA) mounted as close as practical to the antenna in mobile masts or base transceiver stations. A TMA reduces the base transceiver station noise figure (NF) and therefore improves its overall sensitivity ; in other words the mobile mast is able to receive ...
