Signal Routing:
- The input routing to amplifiers is done automatically by the Afracal2 PA
- The output filters are automatically switched in as needed.
- The output signals are automatically routed to the correct in-band antenna for HF 1.6-30 Mhz, VHFL for 30-88 Mhz, and VHFH 88.1-170 / 512* Mhz to ensure the most efficient antenna is connected.
Antennas:
- For the HF Vehicle Station Antenna we recommend the;
- Automatic HF Tuning Antenna
- NVIS kit
- For VHF low band Vehicle Station Antenna we recommend;
- Wideband VHF (30-88 Mhz) Vehicle rod antenna
- For VHF higher band to UHF Base Station Antenna we recommend;
- Wideband V/UHF (100-512 Mhz) Vehicle rod antenna
Power Supply Options:
The Afracal2 accommodates a very wide range of DC supply, 10V – 32Vdc is automatically converted into a stable 24V DC to supply the internal parts as well as the Leopard1 Radio/s connected.
The Vehicle Station can be connected directly to any DC source, however, Sat-Com solutions include some options to ensure uninterrupted operations.
- DC Inverter Charger PSU: With the Base Station Inverter Charger PSU unit installed, the base station operates directly off the 24V DC batteries while the Inverter will provide uninterrupted 240 AC ( 1000VA) to other devices in the command and control room, such as PC’s, Monitors, cellphone and night vision devices, etc. At the same time, the batteries will be charged by the AC charger or the DC/SOLAR charger whichever is available at any given time.
- DC-Direct: In the event none of the above power resolutions are available, the Afracal2 Vehicle Station can be operated from any Vehicle/Truck battery system, 12V or 24V.
- It is HIGHLY recommended to implement the Sat-Com Vehicle Voltage Monitor (VVM) to automatically disconnect the load from the vehicle battery before the vehicle battery is discharged beyond the capability to start the vehicle.
- AC PSU: With an AC Power Supply connected when the vehicle is stationary and AC available, the Vehicle station can run off a suitable sine wave inverter / UPS system and provide continuous operations with the DC Inverter Charger PSU installed. (option1)
While the radio is connected and powered from the Amplifier, their internal radio chargers will charge the radio battery to be ready at all times for hot extraction in case of emergency to facilitate uncompromised communications
