28.10.08 Dual 900MHz 32dB Mast Head Amplifier

Dual 900 MHA comprises two identical amplifiers in one compact integrated package which is easy to transport and install. Amplifier design provides a nominal 32dB of gain, compensating feeder loss and improving coverage. MHA has by-pass functionality to mitigate the effect of MHA failure on cell coverage. Dual 900 MHA has been designed to operate with Nokia Ultrasite & Flexi GSM/EDGE, Flexi WCDMA BTS and Siemens BTS with MFDUAMCO.

MHA complies with AISG2.0 specification.
