Antenna Control Switch, HF/VHF, TX/RX coupler/switch, 1.6 – 88 MHz
This second generation advanced HF switch is based on the proven Comrod product ACS007K. The switch is upgraded with antenna selectors, increased number of IO signals for watch transceiver, storage of the last frequency for each TRX part and upgraded CPU.
The updated HF switch supports the distribution of frequency information from the transceiver to the antenna controller located in the HF-antenna via RS-485 interface. Key information from the antenna controller will be available from the switches front panel, and via Ethernet. In case frequency information is not available from the Tx, the HF switch will carry out frequency sensing and forward this information to the antenna controller via RS-485. Expected time for a frequency measurement is approximately 1 ms.
