Technical Features:
- This rotary Switch has well-arranged input and output connectors, making it easy to see the connection positions.
- This unique switching mechanism provides high isolation between circuits.
- The inactive antenna sid is designed to always be grounded, allowing for stable and efficient switching.
- If any of the four positions have an unused port, selecting that port during a thunderstorm can prevent damage to the radio from lightning. However, selecting this port will not prevent damage to the radio if lightning strikes the connected antenna directly.
CAUTION: Do not change the switch while the radio is in the transmitting state, always check that the radio is in the receiving state before changing the switch. (The switch contacts are all grounded, so doing so is the same as shorting the output circuit of the switch.)
