    I suppose you could use them on a 20-30 foot mast if you feel it is vulnerable to taking a hit. If you want to make your own I suggest some short pieces of stainless steel cable. It does not have to be heavy cable. I make some from 1/8 or 3/16 stainless steel cable. I take a piece 12 inches long or so and fold it in half using a crimp type cable clamp to hold things in place. This makes a loop in the end to use to mount it. I then fray out ALL the individual pieces in all directions.

    Something you might look into are the brushes used by chimney sweeps and some pipeline crews. Different sizes, but I've gotten several about the size of a volly-ball. these happen to have a threaded bolt on the end. Honestly don't have any idea what kind of metal the 'bristles' are, but they are metal.

    Some are a nylon type material meant for stainless steel liners in chimneys so make sure you get the metal ones.

    I just unplug my antennas, nothing will stop lightning from getting to where it wants to go.
