By installing an \u003cb data-path-to-node=\"3\" data-index-in-node=\"389\"\u003eIcom VHF and UHF Pre-Selector\u003c\/b\u003e, network administrators can significantly improve receiver sensitivity and overall range in areas plagued by strong nearby transmitters, broadcast towers, or other collocated radio equipment.\u003c\/p\u003e\n\u003cp\u003eEach 4-cavity module is precision-engineered to maintain low insertion loss while providing steep attenuation of off-frequency noise. These pre-selectors are designed to be mounted internally, maintaining a clean and professional setup within the repeater chassis.
