I have a Magnum Dynalab MD-100 tuner. The Magnum Dynalab ST-2 and Fanfare FM2G are very similar. I tried the ST-2 indoors and outdoors (but not at a high elevation) and it was surprising ineffective. I stayed with my Magnum Dynalab Silver Ribbon, which is directional and brought in a stronger signal. I was very surprised at this result. I did not try the ST-2 on a high roof mount, where it should be more effective. So, if you are really committed to staying indoors, consider the Silver Ribbon. Its only $30.
