Tech Minds: Building a Low Cost VHF/UHF Antenna from Copper Tape
In his latest YouTube video Matt from Tech Minds shows how to build extremely low cost antennas out of copper tape. Rolls of copper tape are commonly found very cheaply in garden stores as slug barrier tape as garden slugs will not travel over copper.
After using a dipole calculator Matt solders coax to two strips of copper tape, resulting in a rudimentary dipole (without balun or choke). His first test with a UHF sized dipole showed poor SWR and yielded poor results on an actual radio/SDR. But his second test with a VHF sized dipole actually yielded decent results.
