How an antenna radiates
Web12 de jan. de 2015 · in this video you can see how aantenna radiates and how em wave propagates in space. WebI've been looking around for antenna ideas and ive seen the ring loop maybe magnetic antennas and was wondering why a deasign like that isnt used for gmrs. i have some knowlege as to how the antenna radiates out but obviously not knowlegable enough to understand why the loops are not used aside from the inline loops on pole thing. Vote.
