I have never done the calculations but I would be surprised if EHS was that
much cheaper than Phillystran after you add in the cost of all of the Big
Grips and insulators. If you also add your time EHS is likely the most
costly option. In my experience the lifespan of Phillystran is more than
EHS, especially in a corrosive environment. Another non-conductive guy
option is Polygon Rod.

I am about to start construction on my new 165ft Rohn 55G rotating tower. My
anchors are 180ft out from the base.
My question is: Just how much is using Phillystrand cable buying me versus
using EHS cable broken up with insulators?
I don't want to cut corners on this installation but the cost on the EHS is
far
lower than Philly and I am sure the lifespan is much longer too.
How about using Philly for 50% out from the tower bearings and then EHS for
the
remaining 50% down towards the anchors?
Any comments / thoughts would be appreciated.
