TheCoplanar Loop. Lo-Z. Since Yagi-Uda antennas tend to lower the input impedance of the feedpoint due to the shunting effect of parasitic mutual coupling, antenna designers have sought ways to raise the impedance to match commonly available transmission lines. Various matching techniques exist including the gamma match, T match, step-up W7LPN2m/440 vertical dipole. The project below is my own design for a dualband vertical dipole for 2 meters and 440. It requires a balun and works very well. I like to tinker, so when I finish one project, I go on to another, even if it works well. There are several methods of constructing a vertical dualband dipole and a simple method is ReviewSummary For : Arrow Antenna 146-4S 4 Element 2 meter Permanent Mount Yagi. Reviews: 24. MSRP: 80.
