This 3D Model is designed to assist in weather-proofing your Do It Yourself - DIY - Quarter Wave Ground Plane Antenna while also adding structure and support to the radiating element and the grounding radials. This can be used on any DIY quarter wave ground plane using a SO-239 or N-Type chassis socket and 10g/12g solid copper wire, for any frequency that these 1/4 wave antennas are made for.. such as the common 2 Meter, 70 Centimeter, 433Mhz, 403Mhz, etc

It is designed in two pieces. The cap (top) slides over the radiating element. The base (bottom) screws into the cap and secures the unit together, adding support for the grounding radials.

For the base, there are two options. Imperial or Metric

The imperial base is designed to accept a 3/4" PVC pipe for mounting. Note that the outside diameter of 3/4" PVC pipe is 1.051 inch.

The metric base is designed to accept a 25mm pipe for mounting. Note that I don't really need a note for metric, because the outside diameter of a 25mm is pipe is actually 25mm. (I cannot test this as I do not have metric pipes available, but it should fit snug. If not, please let me know so I can resolve this.)

You will find information on building a 1/4 wave / quarter wave ground plane antenna via Google or YouTube. They are simple to make and are constructed using a SO-239 or N-Type chassis socket, 5 pieces of solid copper wire, and optionally, a few crimp connectors.

This type of antenna works well for a meshtastic station or repeater, tracking weather balloons (radiosonde), ham radio, listening via SDR, replay test via HackRF, etc. You can use the calculator below to determine the length of copper wire you will need depending on the frequency you are making the antenna for.

Assembly is as simple as placing your DIY Quarter Wave Ground Plane antenna into the cap/top. Run your cable up through the mounting pipe (if you are using one), through the base/bottom (threads facing the cap) and screw the cable into the antenna you made. Now screw the printed base into the printed cap. Now insert the mounting pipe (if used) into the printed base.

I do recommend one tiny bit of silicone sealant where the top radiating element comes out through the cap.

You are now all set to mount this to a pole outdoors and run your wire as needed.
