You said it, Witchdoctor. I've built so many types of antennas over the years it's a wonder the coax and wire haven't wrapped around me like a python ad squeezed the life out of me. It's a nasty habit.
TV line is an often overlooked material for FM antennas. Folded dipoles, J-Poles if you need a little gain, etc....
Give the ham sites a look and check out the DIY antenna designs for 6 and 2 meters. They're easily adaptable to the FM bands. Even a simple ground plane design can give excellent results. At FM frequencies you can build one out of scraps of wire and the female connector that matches up with the male connector on your coax. It takes a couple of hours,at most,to throw together.
