Yagi for 2 Meters
from Ryan St. Arnold -
This antenna makes a great yagi for foxhunting (RDF), or makes a
great base antenna with about 7 db of gain.
3/4" OD or 1/2" ID PVC, about 5 feet.
Hollow Aluminum or Copper tubing, 1/4" or so
Screws and Nuts small enough to fit through metallic tubing
Coax - your choice

The Left Image shows how I placed a
PVC "T" between the reflector and driven element. This allows greater
portability, and if the elements aren't aligned, this will fix that
The Center Image shows how the driven element should be
placed on the boom. Connect a nut and bolt about 1/2" to 1" on the element
as shown. My coax is not shown connected, but to connect the coax, solder a ring
tongue connector on the braid, and center conductor and connect them to the
bolts connected to the element. (Not the bolt hold it to the boom, though only
one of my element coax-bolt is shown, but the screw hole on the top element is
where it approximately should be placed.
The Right Image is how the reflector and director should be connected. I put some
electrical tape on the element where it contacts the PVC to eliminate major
I also connected a piece on the PVC "T" perpendicular to the
boom for mounting on a mast, the length of this piece can be decided by
you. (See the left picture)
