Here's a simple 2 meter antenna that can be made from an old coffee can. Dave Tadlock (KG0ZZ) takes us step-by-step through the design, construction, and testing of this basic VHF antenna made from a common coffee can. He also adds a few suggestions to improve his initial design. If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=Vr7vSu1PBLw. Here are some comments from Dave (KG0ZZ): Ham radio 2 meter antenna made with an old coffee can! Please note: The final length of the vertical element came out to be 25-1/4" (64.1 cm). This is after sitting the antenna on top of a 10' section of PVC pipe and running the coax down through the pipe.

Thanks to Mike (M0MSN) for this "Slim Jim"/"J-Pole" antenna idea. This dual band (2m/70cm) antenna is easy to build and will give you a bit more gain than a 1/4 vertical whip. This variant of the popular "Slim Jim"/"J-Pole" antenna is suitable for both home and field use.

Here are some comments from Mike (M0MSN): HAM RADIO: Easy SlimJim / J-Pole Dual band Antenna Build for 2m/70cm, Thanks to a book I purchased many moons ago, I have found the perfect way to pass a rainy day. make a 2M / 70cm Slim Jim or J-Pole. Not just the standard J-Pole but one that uses a decoupling stub so that you get the maximum power on both bands.......... You need: 1.5M of 300 Ohm ladder line 15cm /6 inches of RG176 or RG316 coax and that's it, Bobs your uncle. Many thanks Mike - M0MSN To get notified of the next upload .clic
