In typical WISP deployments, the WB6-BH-900 is commonly used for links ranging from 10 km to 20 km or more when paired with modern high-performance radios. Why use a 900 mm deep dish instead of a smaller dish? The larger reflector provides higher antenna gain and a narrower beamwidth, improving signal strength, interference rejection, and overall link reliability. This is particularly beneficial for long-distance and high-capacity backhaul links. Is the WB6-BH-900 suitable for 6 GHz deployments? Yes. The antenna was specifically designed to support modern Wi-Fi 6E and Wi-Fi 7 radios operating in the 6 GHz band while remaining compatible with existing 5 GHz equipment. Can I use this antenna for point-to-multipoint (PtMP) networks? The WB6-BH-900 is optimized for point-to-point backhaul applications. For PtMP access points, horn antennas or sector antennas are generally the preferred solution because they provide wider coverage. How does the deep-dish design help performance? The deep reflector improves front-to-back ratio and sidelobe suppression, helping reduce interference from unwanted directions. This allows radios to maintain cleaner signals and higher modulation rates in congested RF environments. Is the antenna future-proof? Yes. Because it covers both 5 GHz and 6 GHz spectrum, operators can deploy the antenna today and upgrade radios later without replacing the antenna, reducing future infrastructure costs. Does the antenna require precise alignment? Yes. Like all high-gain backhaul dishes, proper alignment is critical. The narrow beamwidth that delivers excellent performance also requires careful aiming during installation. Is the WB6-BH-900 suitable for high-interference environments? Yes.
