The yagi 850mhz antenna is super long and super gain designed with careful experimentation and testing. The gain is really super even stronger than the regular 800 900 mhz parabolic grid antenna. It has been compared to the best-selling and most famous local yagi antenna that uses dual driven and triple driven. As a result: This yagi antenna is superior to 6-7dbm for 4g 850 mhz
