Why do I need RF ArmorWith class licensed bands becoming more and more congested, RF Armor is essential in minimising hostile interference from nearby radios and access points. As side-lobe gain is an inherent imperfection in antenna design, the heavy-gauge aluminium is designed to attenuate both inbound interference and outbound transmissions in all directions outside the central lobe. Even in clear spectrum RF Armor helps reduce thermal noise as well as protecting radio and antenna radomes from UV deterioration. Deployment of RF Armor is not only essential practice on any commercial and industrial application, but an expectation as part of the responsible use of class licensed (license-free) bands. Easily assembled, constructed with marine-grade 316 aluminium. Mounting via sector antenna's supplied brackets.
