    Figure 1-1. AW400Tx The UHF transceiver is also capable of receiving RF signals through a 50 Ohm impedance external antenna port. These signals are demodulated and output to the ArWest Communications receiver. AW400Tx delivers a reliable radio link at up to 38.4 kbps over the air for the 25 kHz channel spacing, 30 kpbs for 20 kHz, 19.2 kbps for 12.5 kHz, and 9.6 kbps for 6.25 kHz.

It is shared between user data and unit’s command/status information. All commonly supported baud rates, parity and bit configurations are available up to 115.2 kbps. 2.1.2.

  • Page 20: Antennas

    1. The supply voltage (pins 15 and 16 in user interface connector,) must be 4.2 to 4.5VDC to provide RF output power >500mW (licensed operation mode). 2.1.4. Antennas Antenna type depends on the site requirements, and may be directional or omni-directional. Note that to support 8 miles distance range between Base station and AW400Tx unit, an antenna mast should elevate the base antenna a minimum of 20 feet above the average level of the terrain.
