[TowerTalk] create cr30 rooftop

[Martin Sole]

I'm quite interested in lightning protection. Living in SE Asia we get large
numbers of storms pretty much any time of year, now is a very active time.
I'm not sure that a separate down conductor will be of much use, might
depend on the type of tower you have but Polyphaser produces a document that
suggests this is a rather futile approach unless the cross sectional area of
the wire can approach that of all the other metal work in your tower and
feeders. I guess if it's a rooftop you might need something though.

IF your house is located where lightning also occasionally happens, you
don't want any antenna support structure attached to your house! 


Thanks for the advice ... I have considered lightning ... My research is
that properly grounded, the tower is just a big ligthtning rod and if
anything your house is safer. I plan on taking an additional step and
installing a lightning rod which glenn martin sells at the top of the mast
above the beam and running a seperate ground off of that. Does anyone out
there have additional information about this ??
