The major concern I'd have with the aluminum is its thinness
insofar as carrying "boocoo" current was concerned. It's half the
thickness of our copper strap. You probably don't need 6"-wide
copper strap at the entrance panel. This width is necessary in
commercial sites because of the circumferences of the cables and
waveguide used in those applications. The ground system must have
a surface area equal to and preferably exceeding the
circumferences of these cables and waveguides. If your digi has
but one or two RG8-sized cables, 1.5"- or 3"-wide strap will do
nicely. A 100' roll of our 1.5"-wide copper strap lists for
$100.95. A hundred feet of that aluminum you mentioned would be
$40.00 more. (A 25' roll of that same width strap lists for
$25.95; again, the equivalent length of that aluminum stuff would
cost more.)
By the way, we have a distributor in southern New Jersey who will
knock about 10% off these list prices and will sell you whatever
length of strap you need; so you need not buy more than you
actually require. Contact Ron Block at W.R. Block and Associates
at 800.421.7170. He can assist with technical questions too. His
brother is the founder of PolyPhaser and he's a ham too.
