Same as horizontal polarized types, it achieves a high gain equivalent to 20 elements UHF antenna for home use. By adopting the same housing, it has achieved a significantly smaller size from previous San Electronics products. Great looking design. Not only can it be installed on a wall, but it can also be installed in a variety of locations, such as a veranda (grid) or antenna mast. Even in homes with solar panels, this product can be installed smartly.
