Review on High Power Tri-Power Portable Baofeng UV-5R Two Way Radio for Ham Radio Enthusiasts by Nguyn ng Qun  (D Nhn ᠌

Since the beginning of 2022, it has gone by the name Pofung for export (rebranding is associated with a more comfortable pronunciation of the brand for Europeans). I purchased 18 radios; no feedback. However, you can easily fix the issue by removing the plastic from the tangent connector's back side with a nat file. This will allow the radio's connector, which has a metal clip, to fit perfectly (well, or choose another tongut). connected test: 1) City, 1.85 km away, between a few panel homes and a forest (the forest may not have affected because we have floors 6 and 10). On one na771 walkie-talkie antenna and one normal. The na771 antenna successfully penetrated the transmission whereas the conventional antenna failed to do so (I could hardly understand what was being said). 2) The city, the distance is 9.5 km, between us there are two brick 16-storey houses, a forest, a collection of five-story structures and an industrial zone. The na771 antennae are connected on the sixth floor, and both antennas are connected well on the sixteenth story. 3) Outside the city: the private sector, a forest, a field, and a 4 km drive along the highway had interference in the connection.
