Building a PVC Water Pipe 2M Slim Jim

Below is a 2M Slim Jim built from a five foot scrap of 1/2 Inch Schedule 40 PVC Pipe and #14 AWG Bare Copper wire. The pipe provides the structure and spacer. The wire is glued to the pipe to keep the spacing.

The coaxial feed connection is attached with one small cable ties for strain relief and RTV added after soldering to prevent slipping that might fatigue the connection.

Nylon cord or fishing line support the antenna from the top.

The in band SWR is 1.2 to 1.5 and the 2:1 SWR bandwidth extends beyond 142 to 150 MHz.
