What you should look for is small plasic-encased bumps (each enclosing a
coil) or obvious coiled sections spaced every few inches along the
antenna's length. If it has those, it's probably a collinear like Tom
says, and will be omnidirectional broadside to the antenna. If it
doesn't, and is just a straight piece of wire or rod, it's directional
nearly in the direction of the wire like Richard said.


You won't see that on these colinears, the radome surrounding them
covers it up. I am thinking they may be the coax style colinears, which
would not have the coils.
