20 M - 1 Foot Antenna

mA
mmed

I used 1" copper pipe to make my cylinders. They will fit snugly on 3/4" PVC pipe. The PVC pip will have to be sanded down to allow the copper pipe to fit. I drilled a small hole in the cylinders through the PVC pipe and soldered the wire to the cylinder. I drilled another hole to run the # 14 enamel wire down to the tuning coils.

Wind the coils and tune according to the instructions. See diagram below for details on this antenna. I used the information in Demonstration #4 & #5 to construct this antenna. This antenna is described in Demonstration # 5 from the EH Antenna Web Site.
