CHEAP AND EASY TO BUILD
2 METER ANTENNAS

Are you interested in ultra low cost 2 meter antennas that are easy to build using cheap parts; that require no tedious matching and adjusting; that are almost invisible; that are portable, compact, quickly assembled; and that can be converted into a beam?

If so read on!
These antennas are somewhat based on the "V" designs in other projects on this site.
They include the Ultra-simple wire version in figure 1
The Table Top version in figure 2
The 2 element beam version infigure 3

Fig. 1 Ultra-simple "wire" version above made on an SO-239 connector.

Upper and lower elements must be self supporting. Use aluminum or copper tubing.
Disregard the reference to the upper insulator in figure 2

According to the article, this version had not been tested but should work with a bit of experimentation. It's no more than a standard dipole with a reflector added to come up with a 2 element yagi with all elements bent forward at a 90 degree angle.
CONSTRUCTION NOTES AND TIPS
In all of these designs, please note that the center conductor from the coax connection is connected to the element in the "down...
