[RFI] RFI from HIGH voltage power lines

Just wondering....   I have a few acres that run along HIGH power lines and 
wonder if it is even worth considering building a small weekend 
place/hamshack there.  The antennas would likely be between 100 to not more 
than 250 feet from these guys.

My question is whether RFI is more likely to be generated by these guys 
verses the smaller distribution lines along the average two lane blacktop 
rural road.

These lines are the big guys.  If any of this helps to identify the amount 
of power, here it is.  Probably a quarter mile of more average between 
supports that are three poles each.  Height is estimated maybe about 40 feet 
to the lines.  There are three lines and the outside lines of the three are 
about 31 feet apart.  There are 10 "beads" or "cones" making up each of the 
insulators the wires are hanging on.  There are two cables running above the 
power lines (maybe for lightning to strike them instead of the power lines 
themselves?).  Anybody have any idea of the voltage these would be carrying?

Thanks es 73, de Jim KG0KP
