Comrod antennas
are unique to themselves for the fact that
they have cables that are terminated on both ends. So one you run the
antenna
cable through your boat you can replace your antenna with having to
rerun the
cable. The cable has a PL-259 connector on one side with a BNC
connector on the
other end. The antennas are supplied with a tool to install the
connector on
the inside of the antenna.
