Are you familiar with the FM2G-C? It is being strongly considered. http://www.fanfare.com/fm-2g-c.html This is an omnidirectional antenna, which means it will be very susceptible to multipath. The fact that it is cut for the educational band gives it a little more gain, but, as I said, gain is seldom the problem. The problem is phase cancellation caused by reception of a signal that is reflected by two or more different paths. This causes the signal to actually cancel 100% at certain frequencies. More gain on nothing does not result in something. The solution is a directional antenna, which attenuates all but one of the reception paths, eliminating the phase cancellation. Hmmm...I'm getting a slew of opinions on this, and few of them reach the same conclusion. Such as: http://www.hawaiipublicradio.org/recep.htm I've tried various dipole antennas, all with similar results. Best results so far was an RCA powered indoor TV "rabbit ear" type antenna. I'm tempted to have an antenna cut specifically for 88.3 MHz, as that is the only FM I listen to. Oh well... |
