A few simple techniques can improve FM radio reception including having a proper and well-placed antenna, reducing any interference and switching to mono when necessary. FM radio waves travel in 6-foot wide paths under and around obstacles.
With any frequency, antenna type and alignment are fundamental to receiving a strong FM signal. The instrument should be large and composed of individual elements for proper reception. But it is not enough to merely have the right antenna for the job, as it must be able to intercept the FM radio waves. Ensure that the antenna is not being blocked by any exterior structures or features and has an open view of the sky. At times, switching to mono mode can clear up interference and draw a better signal when just beyond a clear broadcast point.
