I can get roughly go about 900m, my radio will lost signal and trigger failsafe. I would like to upgrade my antenna on my radio and reach more distance. I already ordered the cable and a 8dbi TP link antenna. On the installation part, I have seen some videos on YouTube so I have a rough idea. I am just wondering how you guys did it on the screw on antenna part to get it fit with the stock radio casing? And how much range increase am I looking for?
