SRA 2 B Active Unidirectional Antenna
The antenna shall be an active unidirectional panel antenna with an ultra-linear RF amplifier operating in the UHF range. The on-axis antenna gain shall be 6 dB over an angle of 70°. 17 dB of internal amplifier gain shall allow for the use of RG 58 cables up to 35 m long or RG 213 cables up to 75 m long. The typical line-of-sight range shall be up to 200 m.
The antenna shall be remotely powered through the antenna cable, e.g., from a PS 4000 antenna splitter and feature an LED indicating the presence of a supply voltage as well as an integrated, swiveling 3/8" stand adapter thread, and 50-ohm BNC connectors. The carrier frequency range of the antenna shall be 650 MHz to 870 MHz, its total gain (antenna + internal amplifier) 23 dB, supply voltage 8 V, size 230 x 240 x 26 mm, and its weight 250 grams.
The active unidirectional antenna shall be the SRA 2 B from AKG.
