Abstract: A new and improved Folded Collinear Dipole (FCD) Antenna eliminates a coaxial feed and provides a folded ½ wave top element that is basically two ½ wave elements in parallel above a ?th wave coil isolator another ¼ wave element that is on top of another ¼ wave element that is shielded by a brass feed tube and the bottom element is insulated with a PTFE tube. This is all stacked on top of an RF 50-ohm fitting (Typically an “N” female). A cover/protection tube “G” is made from “cross-linked polyethylene” tubing to increase performance of this antenna as it is nearly invisible to the RF signal and does not attenuate the signal which would reduce overall performance found today in most sleeved monopole antennas. The Vinyl cap protectors are used for mainly two functions, on the main larger sleeve it keeps out any atmospheric conditions including intruders such as insects. The feed tube cap insulates and keeps the element centered into the feed tube assembly.
