I was always fascinated by those rods and bulbs on our old barns, seems all the old farms had them around here, but I never understood how they worked. You answered your own question there, they do attract it, it's what they told me too. The company I attached a link for below, did a protection system on a 13 story building for us in '95. Very nice people, family owned, niche business, had worked out arrangements to work in NYC with I.B.E.W. local #3, was enjoyable to learn of their business. He explained the basic principal of how it works, which is kind of obvious. Apparently that special uninsulated conductor they use is, or was then only manufactured by a few companies, they had a good relationship with one, real specialty business, not a lot of people doing this work. That partcicular cable is specific for the application, must have some unique quality to it, don't recall what it was. A lot of high rise buildings have systems installed, many do not, and I'll tell you it's a darn scary thing when a storm you can't see, rolls up on you when up on a high rise in manhattan, you and 40 other guys are scrambling to get off the steel, not fun at all. Those old Hawkeye bulbs and rods fetch a good price on e-bay, I've got one from our place, had to climb up a rickety roof to get it, it's a keepsake though.

But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
