3 Factors in a Quality Grid Antenna(blogger@L-com.com)
Grid Antenna - A type of antenna which employs an open-frame grid as a reflector, rather than a solid one. The grid spacing is sufficiently small to ensure that waves of the desired frequency cannot pass through, and are hence reflected back toward the driven element.
Grid antennas are very popular for directional wireless applications. They provide a nice, controlled beam width and a high relative gain, and their grid construction makes them resistant to wind. But there are a lot of options out there, ranging from the very cheap to the very expensive. How do you know what you need? What are the factors you should consider before you place your order? We have three suggestions that make sense.
