Don't think you'd notice one bit of difference between bare and insulated
wire as far as the perfomance of the antenna goes.. it's not about ground
contact but capcitance to ground.
I have used verticals with excellent ground screens that used insulated
wire.. and also with bare.. it would not be worth the bother to replace them
now.. just ad more if you can.
