Solution L-com designed a custom antenna solution that met the Apr 25, 2016В В· I cant seem to find a simple dual band yagi made of cheap, easily sourced materials. It has been suggested that I should try a better antenna with my Baofeng before I buy more radio so I'm willing to give it a shot. My antenna making skills are about on the twinlead j-pole and simple groundplane level so I'm not sure how well thi will turn out.

    The Yagi radio antenna is relatively simple to build, provided you learn a few design concepts. The Yagi, also known as a beam antenna, has a directional geometry that works best when pointed at a radio source. It consists of a main antenna, called the driven element, and a set of auxiliary antennas, known as antennas for vhf and uhf radio bands is a curation of 129 resources about , 13 elements VHF UHF Yagi, Shrunken Quad, UHF VHF Folded Dipole, Dish for 10 GHz, Double 5 / 8 Flower Pot Antenna.
