Building simple expedient VHF/UHF antennas, presented by Ron, WA6YOU

Ron Payne, WA6YOU, a nationally recognized expert in building coax interconnects and antennas, demonstrates how to build quick and easy Ground Plane (GP) UHF/VHF antenna.
Ron demonstrates how to calculate length of the antenna elements, prepare copper wire for soldering, put the antenna together, and tune and measure it.
At the end of this short presentation he ends up with a perfectly tuned antenna for the 70cm HAM radio band.
