And, of course, add to this that pylons are spindly and what ? 60 feet tall

Over 130 feet for a typical 400 kV pylon. Nearer 100ft in rural areas.

Very crap and variable conversion from m to ft there - 50m & 46.5m

*Over 160 feet for a typical 400 kV pylon. Nearer 150ft in rural areas.*

Slightly lower profile towers have been used more recently.

Ground clearance is a minimum of 25ft at 400kV and nearer 40ft in most cases

*Conductor* ground clearance (it sags!)
