I ran across this on wifihorizon.com which seems to suggest that antenna length would be a factor:
I wonder if this goes both ways (can an antenna be too long?) or if this simply means there's a minimal length depending on the application and/or wavelength? Obviously I'm stumbling around in the dark on this one, so feel free to set me straight if I'm missing something.Wavelength and antenna length go together.To oversimplify, the longer the antenna, the more of the signal it can grab out of the air. Also, antenna length should be in whole, halves, quarters, eighths, and so on of the intended wavelength for best signal reception. The highest reception qualities come from a full wavelength antenna.
