Review on 📶 Hawking Technology Hi-Gain Dual-Band 9dBI Directional Antenna Kit for Improved Connectivity (HD9DP) by David Turner

Performance was very poor. it is directional, but it is not clear that the antenna has both horizontal and vertical polarization. I can only assume they add horizontal and vertical reinforcement to get their numbers. in practical use, the strongest signal received directly in the direction of the antenna is only 1/2 the power of a standard 3dbi antenna. I avoid this if all you're looking for is blocking signals from an angle and you don't care about gain at all.
