What I really meant was, "What frequency bands are the antenna you're using designed to work with". From the picture it's just a whip antenna, meaning for optimum reception it should probably be much longer.
A quarter wave whip would be 1/4 of the wavelength of the signal you are trying to receive, 3e8/(100e6) = 3m wavelength, so 3/4 of a meter or about 2.5 feet (just like the antenna on your car ;) ). If you just want to see if it works I might suggest getting a length of wire and cutting it to size, then strip the end and push it into the connector slot. You could also get one of the collapsy antennas you find on boomboxes and the like and hook it up. The problem you will run into is that the SMA connectors are usually used in HF/RF applications, so you will need some sort of adapter. If you want to build a fancier antenna (still easy to do), just google 'FM antenna' and you will get lots of sites explaining both the theory and construction of FM antennas Using an appropriately sized antenna will greatly increase your signal strength.
