高增益天線和普通天線的區別，就是高增益天線增益高些，距離可以更遠，但犧牲了波瓣寬度；普通天線增益低些，距離近些，但波瓣寬度，也就是對四周覆蓋範圍大些。

The difference between the ordinary high-gain antenna and the antenna, high-gain antenna gain is higher, the distance can be longer, but the expense of the lobe width; low antenna gain more general, recent distance, but the width of the lobe, i.e. on the surrounding coverage bigger.

The difference between a high-gain antenna and a normal antenna is that the high-gain antenna has a higher gain and can be farther, but at the expense of the flap width, while the normal antenna gains a lower, closer distance, but the lobe width is larger.

The difference between high gain antenna and common antenna is that the gain of high gain antenna is higher, the distance can be farther, but the lobe width is sacrificed; the gain of common antenna is lower, the distance is closer, but the lobe width, that is to say, the coverage area around is larger.
