Hi, I have a Lectro Venue and it's complicated to turn on and off the antenna power (12v) on it, it needs a disassemble. I know the passive SNA600a can handle that, but tomorrow I need to use the Bowtie passive antenna, and I didn't find information if that has the protection or not. Waiting from a reply from Betso, but not sure it comes in that short time. Mostly I use my Sharkies that's why I don't really want to change things. Thanks
