If you live in an area that  could see a wildland fire, you definitely want some EHS at the ground to about 15ft  off the ground and even then it might not matter if the fire is hot enough.

According to the BIBLE (Rohn) product catalog  @ 100 ft.  of R45- Zone B 40FSF 
= three layers of  1/4 EHS. = 6650 lb  tensial strength
So IMO PhillyStran  HTPG 6700 should be used for all three levels of guys.   IF you 
chose to use ¼ EHS   the info for none resonante   
info on lengths  on this link.

I have advised hams who do not have  ANY material on hand  as a sugjestion to 
go  to R-55 at 100 ft level.
Why you only need TWO levels of Guys and If you  compare the cost of  TOWER . EHS 
guy wire 50s insulators and Crosby  cable clamps (6) for each insulator and (3) for 
each   or substute PLP line products BIG grips  .    Then the two levels you need 
with R-55 end use EHS with 502 insulators  and cable clamps on  R-55 and the 
Phillystran and the PLP big grips 18  and 9 conventional  PLP ¼ EHS  Big grips 
9 502 insulatore.

It’s all about the numbers   BUT imo the installation would only be built with 
¼ EHS and only 6700 Phillystran.

In an off list email, I advised pretty much the same.

Happy Holidays Scott!

I'd recommend Phillystran for the top guys, but EHS the first few feet from the 
tower, and up about 15 feet from the ground. The former protects against 
something getting dropped from the tower, the latter from vandals and other 
animals. I'd probably do that with the middle guy, as well. Otherwise, be sure 
to break it up with insulators into non-resonant lengths.

For shunt feeding, all the guys definitely need Phillystran or an insulator 
near the tower. Even the lower guys, though, should be broken up into 
non-resonant lengths with insulators.

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.
