For years, Channel Master had that base scanner antenna that was a fan VHF / UHF fan dipole, and it looked like a squashed star, but was very popular. Many municipalities used them. I have heard of folks TX'ing on them, albeit 20W, or less, since they had matching baluns on them. My 1st outdoor wide-band VHF / UHF scanner antenna was just a 30" car antenna 30ft up a fur tree. That actually worked great to RX 37MHz EMS, 46MHz fire, 35MHz McDonalds drive-through, 46 / 49MHz cordless phones, 2M HAM, VHF high police, fire, businesses, Conrail trains, VHF AM airplanes, (Especially the chit-chat 123.450MHz FREQ.), even 170MHz radio station remote broadcast links, and UHF HAM, business, GMRS, and TV audio. Ya know, it wouldn't be hard to make such an antenna.
