Bring your parts to project night and we'll help you solder all the parts together. Gideon Kohler KJ6ZBJ is our resident J-pole expert and is always happy to help you out. If you want to make a J-Pole, give us some advance notice so we can make sure that Gideon can be there.

The elements are constructed from an old tape measure. 1 inch is best at the elements will keep their shape in the wind. 3/4" also works

The frame is a piece of PVC tubing with a couple of crosses to mount the elements on. Elements are held on with hose clamps.

Step 1

Cut an 11 1/2 inch, a 7 inch, and two 5 inch pieces of PVC pipe. Before cutting the pipe, it might be helpful to measure and mark the length using a sharpie black marker.

Step 2

Glue an end cap on each 5 inch (short) pipe.

Step 3


Glue the two long pipes together using a cross connector (as pictured).

Antenna Romance

Two antennas met on a roof, fell in love and got married. The ceremony wasn't much, but the reception was excellent. Since they were a perfect match, soon they generated harmonics. Wrapped the harmonics in dipoles. But later the harmonics turned out to be parasitic elements. The true story -- she was a tri-bander and he felt trapped, so they went on separate beam headings
