[TowerTalk] Has anyone made use of aluminum pole to house wire?

[John Hensley]

We recently had our utilities run underground to resolve some problems.  Left is a coil of 5/16" diameter stranded aluminum power line, about 100' or more.  Twoof the wires are black insulated, one is the ground return.
Is this stuff suitable for guying a tower or making a "last forever" wire antenna ofsome sort?  
Would enjoy hearing responses to this.
TIA,
John
