Kerry,
Not planning on spending any big bucks on a radial system. I have a bunch
of used aluminum fence wire that I save as the goats and sheep tear up the
fencing system. I probably have enough for 24-30 fifty foot radials that I
will bolt to a square piece of aluminum with the center cut out. I'll use
stainless bolts and nuts an put some extra NoAlox on each bolt joint. I
have the big garden staples for holding the radials down. The Hustler 5-btv
is 24 feet high if I remembere right. The single most expensive part will
be the stainless hardware. I will probably check Ebay to see what is
available there.
BTW, there is a wire fence within easy range of the antenna - would it help
to attach to that also or is there too much chance for wind to make the
fence move a little and introduce QRM??
Thanks for responding. 73's
