I installed a Magnum Dynalab ST-2 Antenna in my 16 it's hooked up to a Jensen MSR2007 Modular AM/FM/iPod stereo. It works very very well, much better than anything else I have use. Including the Shakespeare Galaxy 4' AM/FM Antenna. http://www.magnumdynalab.com/fmantenna-st2.htm

Nice. Looks like a METZ antenna.

Visually the Magnum Dynalab ST-2 antenna appears identical to a METZ antenna, particularly in the mounting, the coil, and the whip attachment. I am almost certain that it is a private label version made by METZ. I do not find that the mounting bracket used with the Magnum Dynalab ST-2 is particularly well thought out for mounting to a small boat.
If you are seeking a vertically polarized antenna specifically tuned to the FM Broadcast Band, you can also take advantage of the GAM ELECTRONICS design. In my opinion, and based on two years experience using the GAM ELECTRONICS SS-2 antenna with an ADAP-II mount, their design represents a best configuration for mounting to the typical 1-inch, 14-TPI threaded base mounting units which are just about universal on boats. The GAM antenna provides a much cleaner mechanical mount and can utilize standard marine base mounts and extensions.
The GAM ELECTRONICS antenna tuned for the FM Broadcast Band is their model FM.
The principal difference between the SS-2 and the FM models is the length of the whip. In the SS-2 VHF Marine Band model the whip is about 37-inches long, and in the FM FM-Broadcast Band model the whip is 54-inches long. The difference in the whip dimension corresponds to the difference in the frequency band:
FM Broadcast = 88 to 108 MHz
In the case of the GAM ELECTRONICS the antenna will be tuned for 50-ohm coax, not 75-ohm, but this should not make any difference when used with a typical FM Broadcast band receiver.
