A land mobile radio system (110) includes a plurality of receive antenna (120) for receiving RF signals transmitted from mobile units. Each receive antenna (120) is connected to a transform matrix (133) which divides each received RF signal into a number, N, of transformed signals, each transformed signal containing an equal power level part, 1/N, of each received RF signal. Each transformed signal is provided to an amplifier (135) for amplification thereof, and the amplified transformed signals are provided to an inverse-transform matrix (138) which recombines the equal parts of each amplified transformed signal into amplified received RF signals which are provided to an RF signal processing section (125). The amplified RF signals are thereafter provided to corresponding radio channel units (127).
