NB4改天线

就是拆开 打孔 插天线座 没了 麻麻在也不怕定向天线背对着车没信号了（原装NB4功放有两个天线座管他呢全插了）

可以说毫无效果，用了就知道了

测试了一个早上的车距离提升明显目前两百米左右还是满格（广场只有这么大）现在全方向信号还是满格不会出现原来定向天线遥控器背对着车没信号问题。

还有第二个天线座是空的插上去没用https://app.rcfans.com/public/emotion/face_wulian.png

单独改天线，提升不大，建议加增程模块

非常666，楼上更牛

再远了 车都看不到了

我的經驗
換了這種天線平均值約多2個dB.
多加個2W的放大器平均值約多10dB.
實測多一陪距離（場地不同， 時段不同時有不同效果）， 場地週圍是空廣的時會多過100米（車子變太小看不見沒再控遠點， 原來只控幾十米）， 不過都有延時問題。

车控100m左右已足够,再远车都看不到
