Grey PVC Sang-v SWR Vent Cowl, For Construction, Manufacturing Unit

SANG-V SWR vent cowl, also known as a SWR cowling or SWR terminal cowl, is a type of weatherproof cover or hood used in radio frequency (RF) and microwave systems to protect the end of a coaxial cable or waveguide from the elements, while also helping to minimize the occurrence of standing waves and reflections. SWR vent cowls are typically designed to be installed at the open end of a coaxial cable or waveguide that is terminated into free space or an outdoor environment, such as an antenna or an outdoor RF transmission system. They are typically made from weather-resistant materials, such as metal or plastic, and may feature a flared or conical shape to reduce reflections and improve RF performance. The primary function of a SWR vent cowl is to protect the exposed end of the coaxial cable or waveguide from environmental factors such as rain, snow, dust, and debris, which can degrade the performance of the RF system. Additionally, SWR vent cowls may include features such as drain holes or filters to prevent moisture buildup and improve airflow, while minimizing the ingress of foreign objects.
