Well, almost nothing. I wanted to take part in a club net on a 70cm repeater but the only rig I have for that band is a VX-2 HT, which only puts out 375mW. I couldn't hit the repeater from my QTH using the whip antenna but I don't have much money to spend on ham gear these days so I hunted around to find something I could build with what I had on hand. The result is this oddball combo of a quad and a yagi, called a Quagi, which I built with about 10 feet of #14 copper wire, a 4-foot hardwood dowel and some duct tape. Damned if the thing doesn't work!
