My Antenna Designs

Below is a list of antennas I have made, along with rough instructions on how to make them.

Dual Band PVC/Tape Measure Yagi

My homemade 2m70cm 3 element yagi antenna on top of Osterhout Mountain. I was able to pull in signals from Hazleton and Lake Wally!

This is my 2m/70cm PVC and Tape Measure yagi antenna. It is simply five 1-1/4” PVC crosses cemented together at the appropriate lengths, with tape measure segments clamped on the crosses to act as the elements. My design is based heavily on other PVC and Tape Measure yagi antennas found across the internet. It is able to be oriented outwards, or straight up for satellite communications. With this antenna, I am able to receive communications from Hazleton in Tunkhannock!

Weatherproof Portable 2m70cm Dipole

TODO

This is an antenna I am in the process of making. It will be completely sealed, easily transportable (compared to my monster 2m70cm yagi), and able to hang from trees for easy deployment.

Extension Cord Adapter Antenna

My homemade PL259 to standard US female plug adapter. This allows me to use any outdoor extension cord as a shortwave antenna. It works well enough to pull in stations that I couldn’t hear otherwise!

This is by far my least scientific antenna. My homemade PL259 to standard US female plug adapter. This allows me to use any outdoor extension cord as a shortwave antenna. It works well enough to pull in stations that I couldn’t hear otherwise!

It is simply an RG8X cable soldered to the end of an extension cord, with the proper connectors. The coax cable is soldered to the ground wire of the extension cord. The coax shielding is unfortunately ignored, as soldering it to any other wire would create a ground plane directly next to the main element.

Eventually I will create one of these with two back-to-back female plugs, to allow you to make a proper dipole out of extension cords!
