External FM antenna
The waveradio I own has a 1/8" 75 Ohm female connector on teh back panel. The external antenna I purchased (a TERK product) has a typical 75 Ohm coaxial male connector.

The fix for the problem is simply go to Radioshack and purchase their part number 278-267 which is an "F" jack to 1/8" Male Plug. The cost is $6.09. This should solve your problem. The 75-Ohm antenna plug can now be screwed or connected to the "F" connector.
Bose Customer Service (800) 444-2673 can provide the correct antenna for the unit.
