Simple 2M Ground Plane Antenna


If you are just getting experience in building antennas or you are an old pro, here is a simple and fun project!


This antenna is perfect for those hams living in the primary coverage area of the repeater for 2 meter use.


This antenna is nothing more than the old standby "Droopy Groundplane" and can be used on any band where it's physical size does not pose a problem.


Remember that the vertical radiator is 1/4 wavelength long at your operating frequency.


It has no gain but makes an excellent small antenna that can be mounted just about anywhere and with a little planning, can be used mobile on a short mast from the bumper!!


Adding a small attachment loop at the tip of the radiator will enable it to be suspended from above for inside use.

Build it! (See drawing)

The vertical element and radials can be made of #12 copper wire or welding rods, coat hanger, etc.


The vertical radiator (A) should be soldered to the center connector of the SO239. The four base radials (B & C) and (D & E) can be soldered or bolted to the SO239 mounting holes using 4-40 hardware.


The four base radials then should be bent downward to a 45 degree angle.


The antenna can be mounted by clamping the PL259 to a mast or even passing the coax through a 3/4 ID PVC pipe and compression clamping the PL259. Either way let your creativity work for you.


If you plan on mounting it outside, apply RTV or sealant around the center pin and PL259, and tape well, to keep water out of the coax.
