Re: Lightning protection- precision 18
Why a temporary Faraday cage? Back in ham radio days, our entire rig lived inside one. Why not make one out of wire mesh to protect your electrics all the time? If lightning approaches, unplug antennae & power, you're done. Nothing to search for, assemble, install, disassemble and store. Maybe make it big enough to store at least some of your portables, too.
Just a thought, your mileage may vary.
As mentioned above, I do disconnect everything: antennas, power supplies, grounds and the copper foil ground plane of the SSB. I'm thinking more along the lines of individual containments for pieces of equipment. For my small h/h gps and my h/h vhf, I've just cut empty food cans that telescope inside one another. By cutting two cans and crimping the end of one, I've been able to create really tight tubes, the smaller fits inside the slightly larger. Wrapping the elec. device in 6 mil poly in the smaller tube and wrpping it in 6 mil poly, creates two insulated layers. The can setup is easy to open and close and should provide Faraday protection. For my EPIRB, small computer, plotter, and Pactor, I just found an old heavy duty steel Milwaukee drill case (drill died long ago)which I've fitted with padding to fit the devices. With the devices in plastic bags, it should at least provide one layer of protection. I have to believe the heavy steel case is better than aluminum. As for the SSB, it's too darned big to be lifting into some sort of shielding every time a storm gets near so I think I'll make a 1/2" hardware cloth enclosure for it. The antenna tuner is really not in a very accessible place, so attempting to protect the SSB is probably futile. Hope I never have to test the theory but it's worth experimenting.
