anythoughts on the ffect of putting long wire anttens near powerlins ?

thanks you changing poles (and leaing the an old pole I have access to
a pole for a posible HF antenna that will terminate near thw power line
(and likely run away from them at a roughly 90 degree angle, groow
effect like the power line falling on the attenna are adressed by the
phycal layout but what of the rf efect (a seperate from the end of the
attnea on the old pole to the restrung wire new pole is a bout 4-6 feet
( the anttena is still in the planing stages)
