This video does a pretty good job showing how to make your own 5/8 wave 2 meter antenna for your car. At the heart of Amateur radio is experimentation. Here is an easy project you might want to try.
From watching the video and listening, I came up with a list of materials. If you have a good source for these, let me know in the comments. If they are a good source (could be Amazon, scrounging for junk, local hardware store, etc), I will update the post with information about that I have not built this yet, but thought it might be something to try sometime.
Materials List:
- Mobile antenna base
- Fiberglass rod 1.4 meters long. Comments on the video suggested you find something similar to driveway markers.
- Outer coax braid.
- Enameled copper wire approx 40 cm
- Heat shrink tubing
- Solder and soldering iron.
- Gorilla glue.
