The Sleeve30 kit for the mANT30 parabolic antenna will enhance point-to-point link performance by reducing noise and will also reduce impact on adjacent RF devices by removing the side radiation from the antenna. Additional and co-channel interference creates unwanted signal attenuation that causes decrease of link quality and speed. Using Sleeve30 Kit with mANT30 gives 22 dB additional selectivity for each mANT30 in a critical direction. Using Sleeve30 Kits for two mANT30 devices side by side provides extra 44 dB selectivity. Such improvement allows several mANT30's + Sleeve30's to freely work at one place, at the same channels, without interfering with each other. Sleeve30 Kit also reduces wind load and protects the antenna reflector and feed from harsh environments, improving PtP link sustainability. Sleeve30 shell is made of corrosion-resistive, lightweight aluminum; the front cover has excellent RF signal transparency.
