High Performance Dual Band Slim-Jim Antenna Mount
It goes without saying that a antenna needs a means of mounting said antenna. This photo shows the mounting arrangement that I use for my 1/2 wave 2 meter/70 centimeter Slim-Jim antennas. The mount is made up of 1/4 inch aluminum plate, that I assemble by tig welding the aluminum pieces together.
When I build these antennas, I add a length of coax in the bottom section of the PVC pipe, connecting the bottom RF SO 239 connector to the radiating element, allowing the mount to be adjusted up and down along a 12 inch section of the PVC pipe, so that the mount does not disturb the electrical characteristics of the antenna.
