install a99
 

I want to install a A99 antenna I was given by a friend. I have a 50 ft
tower I want to put it on. Go to QRZ.COM, lookup my call sign (KI4CXZ)
and you can see my mast. I really don't want to put this antenna at the
top. About 3/4 way up. Is there anything to be concerned about how far
to mount it out from the base. Thanks and "73"
