Antenna Remote Disconnect for Lightning Protection

Posted date: May 04, 2016in: NewsNo Comments

A single lightning strike can destroy thousands of dollars worth of radio equipment. Experienced amateur radio operators know the only sure protection is complete disconnection. This can be a chore, especially when multiple antennas are involved. As well, it is all-to-easy to forget to do it. This system makes it possible to accomplish hands-off multiple antenna disconnects and re-connects either on-site or remotely. It also provides for antenna rotator connect/disconnect. The on-site mode can be wired to automatically connect antennas when the radio equipment is turned on and disconnect them when the radio is turned off. The remote mode requires a web IP switch which is controlled by a PC or smartphone. The result is excellent lightning protection at any time from any place.
