This small dual band UHF VHF directional antenna is good choice for portable operations. This antenna is composed by a moxon antenna for the two meters band and it includes two parastatic elements for 70 cm band.
The antenna I built was inspired by a portable delta loop designed by Doug DeMaw, W1FB. Given that I constrained myself to a 50-foot roll of speak wire, I scaled my antenna for the 20M band. Using the formula, 1005 divided by the frequency in megahertz, I calculated a total length of 71 feet (21.6 meters) for the center of the 20M band.
Surprisingly, although PCB soldering is the core process of electronics assembly, few people do know how to solder reliably
