I would go with the comparable EHS diameter / strength, e.g 1/4" EHS in
Phillystran such as 1/4" 6700 PSI. I have used Phillystran for, say, twenty
years and have never had a problem, specifically breaking. I believe it
to be a good as, if not better than
comparable steel EHS>

I rather doubt you will EVER see Rohn spec something like Phillystran.
There is a risk IF CARELESS of cutting the Phillystran cable cover when in
particular, lowering antennas and having the covering scraped or cut by
nuts/bolts/sharp edges of the antenna. Construct your antenna to not have
any nuts facing down or sharp edges. Watch very close when elements are in
proximity to the Phillystarn.
It is recommended that EHS be installed near to the guy post so as to avoid
the 'Philly' catching fire in the event of a grass fire.
I consider both of these situations rather minor, if proper recautions are
taken.
Anticipating hanging wires off your tower...sometime in the future: Philly
is the only way to go to avoid any interaction, etc. at least for the first
30 feet or so FROM the tower.
