I got an old Archer(Rat Shack) 1/2 wave antenna in on trade. It's in good shape, except the 3 radial (ground plane) elements are gone along with the 3 "top hat" rods. I downloaded a manual which dosent show the length of the radials. They appear to be ~3 to 4 feet long. If anyone knows the length of them, I would be greatful for the info. The length of the top hat rods may not be too critical....but that info would be a bonus Thanks in advance, 73s, Pluto
