hey richard
unless you already own that wire i would suggest going to homedepot and
getting a 500 foot spool of 12 ga insulated wire it is only about
15$-20$ and its stranded wire so it will take the stress and strain
better than a solid wire would
good luck
BTW i am putting up a similar antenna 1/4 wave for 160 inverted L feed
at the ground center radiator going up 40 feet along the tower then 83
feet to a support and about 8-16 ground radials
73
