The J Pole Portable Antenna Stand

By N6JSX /8 06/2012

The 2m/440 copper-pipe "J" Pole is truly a simple and most effective antenna that does not require any counterpoise radials/ground. When I'm on the road as a Contract Engineer I take a J Pole antenna, 50w mobile and an Astron VS12M with me. Most extended stay motels/apartments will not allow mounting any antennas to their structure. Leaning a J pole against the wall compromises the low angle radiation pattern of the J pole. I solved this by making a solid but removable stand for the J pole allowing me to place it on the patio, balcony or in the corner as a hat stand.

The PVC stands (and hat rack antlers) are made from 3/4" PVC, elbows, cross, 45-angles, end-caps, 1/2" thread adaptor, PVC glue, and some brown spray paint.

The key to these stands is the use of copper-pipe 1/2" CXM copper adapter soldered to both ends of the long J pole element that allows the use of threaded PVC fittings.

I placed a copper sleeve (only soldered to the lower section) in the middle of the long J element. The J pole breaks down into two 40" copper pipe pieces. Now I can easily unscrew the PVC parts from the J make and make all easy to pack and ship!

NOTE: the PVC gluing of the legs can be tricky to insure the legs are placed properly during glue drying to insure the J pole remains balanced and perpendicular to the floor. I hung a bubble level on the long J pole element to insure dead-center balance alignment. The great thing about PVC is if you mess up it was a cheap mistake to replace/repair!
