To avoid this we needs to check the Signal Quality and Signal Strength time to time. This is most common problem which results freezing in channels.<\/p>\n<p style=\"text-align: justify;\">If satellite dish is fine tuned then there may be a interference problem. Due to interference of other frequencies channels gets freezing. This problem generally we gets in <a href=\"http:\/\/headendinfo.com\/freezing-sahara-channels-border-side-areas\/\" target=\"_blank\" rel=\"noopener noreferrer\"><span style=\"color: #0000ff;\">Border Side Areas<\/span><\/a>. To avoid this we need to use TI filter or Terrestrial Interference Filter.<\/p>\n<p style=\"text-align: justify;\">If your LNB is not ok then also you can get the freezing of channels or loss of signal. You need to check the RF port of the LNB first make it clean. Because sometimes there may be carben in RF port. This carben reduces your signal quality and signal strength which results loss in signal and freezing in headend.<\/p>\n<p style=\"text-align: justify;\">If you are using the TI filter then open it and make it clean from inside there may be dust inside it.<\/p>\n<h3><strong>Splitters<\/strong><\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"1759\" data-permalink=\"https:\/\/headendinfo.com\/reasons-freezing-headend\/2-way-splitter\/\" data-orig-file=\"https:\/\/i0.wp.com\/headendinfo.com\/wp-content\/uploads\/2017\/09\/2-way-splitter.jpg?fit=338%2C368&amp;ssl=1\" data-orig-size=\"338,368\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"2 way splitter\" data-image-description=\"\" data-image-caption=\"\" data-medium-file=\"https:\/\/i0.wp.com\/headendinfo.com\/wp-content\/uploads\/2017\/09\/2-way-splitter.jpg?fit=276%2C300&amp;ssl=1\" data-large-file=\"https:\/\/i0.wp.com\/headendinfo.com\/wp-content\/uploads\/2017\/09\/2-way-splitter.jpg?fit=338%2C368&amp;ssl=1\" class=\"aligncenter wp-image-1759 size-medium\" src=\"https:\/\/i0.wp.com\/headendinfo.com\/wp-content\/uploads\/2017\/09\/2-way-splitter.jpg?resize=276%2C300\" alt=\"2 way splitter\" width=\"276\" height=\"300\" srcset=\"https:\/\/i0.wp.com\/headendinfo.com\/wp-content\/uploads\/2017\/09\/2-way-splitter.jpg?resize=276%2C300&amp;ssl=1 276w, https:\/\/i0.wp.com\/headendinfo.com\/wp-content\/uploads\/2017\/09\/2-way-splitter.jpg?w=338&amp;ssl=1 338w\" sizes=\"(max-width: 276px) 100vw, 276px\" data-recalc-dims=\"1\" \/><\/p>\n<p>The first splitter which we are using after the LNB it can be faulty.
