More Gain, More Power - 2m S2S Madness

The yagi is a homebrew design made from U-channel aluminum, steel hardware, and arrow shaft elements. The matching network is made from parallel 1/4 wavelength sections of 75 ohm coax to transform the 28 ohm yagi impedance up to 50 ohms. Those coax sections are wound a few times through a toroid as a common mode choke. The boom is about 8 ft in length when extended and folds down to 32 inches. total weight of the antenna is about 2 lbs, and the pool cleaning pole mast adds another 2 lb or so.
