RF Central will be showing its RFX-RMR-II line of rack-mounted receiver units at NAB. The receivers work in the 2 GHz and 5.8 GHz bands and when combined with RF Central's transmitters allow high quality, low-latency transmission of SD and HD digital video. The 2 GHz receiver is primarily designed for use with ENG news remotes while the 5.8 GHz band is often used for live sports stadium and arena coverage.
