The HyperLink indoor 2.4 GHz 8-Pole Ultra-High Q Wi-Fi channel filters are ideal for co-located equipment installations. Available in seven versions for Channel 1, 3, 6, 9, 11, 13 and 14, they provide excellent adjacent channel rejection. By reducing interference from both inside and outside the band, improved performance of co-located equipment can be achieved. These bandpass filters are bi-directional, so either end can be connected to the antenna. These filters are designed to be installed indoors or in weather-resistant enclosures.
