Review on 📻 High-Performance Quad Band Antenna for QYT KT-7900D Mobile Radio - 144/220/350/440MHz +RB400 & Cable M5 by Jason Pinkney

I bought this antenna for a QYT tri-band radio. It works fantastic! but sometimes I'm not sure what kind of antenna it is that has a lot of noise. If I put my hand on it without passing, of course! The noise disappears. I checked that everything is grounded, but I think the antenna is sensitive to the environment and needs an additional ground. The rest works great! So in my opinion a great antenna but it takes attention to detail when you have to work with so many bands. Ground antenna better. Most other antennas do not require special attention for proper grounding. Buy it, it's worth the money.
