好像没说功率大小,前边一个能发29km,后边一个也是16km,估计功率不小

我觉得像5428,

很好奇家用频率如何能够达到18英里~

看起来天线也不是很BT阿

对讲机的“距离”都是乱标的,不可当真。
GMRS,印象里限制发射功率1W。
接收性能做好一点,如果是两个山头,直线无阻挡,距离是可以达到很远。

即使实际能有10km也很NB了啊

MOTO的TALK ABOUT 如果仔細看,其實並不是MOTO生產的,事實上那是衣間在中國的廠商製造的,並且只是打上了MOTO的標誌,應該說是MOTO授權生產的,所以性能其實真的不好。
廠商的宣傳不可盡信,MOTO在某產品上宣稱產品 up to 2 watt
但實際上卻只有0.63瓦,這可不是MOTO不曉得喔,送美國FCC審驗的時候報告裡面可是寫的一清二楚的。
更何況這樣的設計,或許可以打的很遠,但是要地形配合,這裡所謂的通訊距離,
指的是直線,那是特意挑選出來的地形,因為在地球上兩個身高180的人站在平地上面,可以見到彼此的距離應該不超過七英哩,UHF是所謂的直線波,如果不能看到對方,那麼訊號就到不暸了。0.63瓦的GMRS無線電就可以打到14公里,不過這樣的機器再都市裡面能傳到五百公尺就很偷笑了。

推薦如果要用,可以尋找一般的MOTO出的早期兩瓦的無線電,真正可以收發兩瓦,對於在都市裡面的一般生活應該可以使用了,但是如果要在郊外用,或許還是選擇VHF頻段的無線電會比較好一點。例如YAESU VERTEX VX-170之類的無線電
