4m Slim Jim Antenna
This 4m Slim Jim is cheap and easy to build yet it greatly out performs the more usual dipole due to its low angle of radiation. An SWR of 1:1 is obtainable across the 4m FM band with simple adjustment. The photograph and PDF diagram show the construction, however a brief description is also given.

6m/10m Dual Band mobile whip
This antenna is made from either an old CB whip or a stripped-down 2m 5/8 whip. When you strip down and re-shrink an antenna, be careful because some heat shrink tubes can change the antenna’s resonance, especially with helical windings. You can use a piece of 20mm conduit for the former of L2 with a
2m Folded Dipole
Simple 2 meter folded dipole antenna
Six Meter Yagi Antenna
A four element Yagi Antenna for 50 MHz band. The reflector and the director elements can be mounted directly to the metallic boom, while the Driven element must be insulated from the boom. The driven element is basically a simple folded dipole and foreseen a 4:1 balun. Usage of a folded dipole as driven element
