On the question of "Will the EHS cause interactions" - the answer is YES.

That is true regardless of length, although the magnitude of the interaction is going to be a factor of many things including the length and proximity.  It's possible to pick lengths that minimize the impact depending on band, etc.

So if you plan to mount a beam among the guys, definitely use insulated guys like the Phili stuff as that takes interaction problems off the table for the most part.

Good luck!

You should do your homework before trusting any installer, this information is readily available. Rohn's catalog will clearly answer your question regarding guy locations and the EHS type. This varies by wind speed and wind load. If you are going to have side mounted antennas I would definitely use all non-metallic guys.  See the Phillystran catalog for the equivalent kevlar cables and proper installation techniques.

I want to have a 100ft 45G installed on my new property. It will hold JK
Mid Tri 40 on top. I plan on adding a Yagi with a  swinging gate at lower
level later, and perhaps shunt loading for 160 and 80m.

My installer wants to use 3 sets of EHS wires. He is ready to substitute
the top one with Phillistran. So here are my questions:

Are EHS guys likely to cause interactions with top and medium beams?
Do EHS guys compromise tower for 160M shunt feeding?
Do I need 3 sets of guys?
Should I move to Phillistran?
Is Phillistran 7000 lb on top and 4000 at bottom good enough?

The installer wants to build the tower with the beam on top. Have the beam
at 3 ft, then raise to 13, 23,....Perhaps that's why 3 sets of guys. The
location is in E GA, with relatively low wind.
