Detailed Product Description

The FLB-390 is a new air launched ground penetrating antenna  to cover the need for non-contact antennas in applications where full contact is not possible. Despite the fact that the antenna is air launched it has extremely good side lobe isolation properties. Thanks to the fact that the antenna beam is very narrow and and the front to back ratio extremely high it can be used in crowded environments where other antennas might not be up to the task

The FLB-390 is a feed loaded bowtie antenna specifically designed to be used in areas where ground coupled antennas are difficult or impossible to use. The steady signal and high directivity of this antenna makes it an excellent choice for layer detection and cavities. This antenna is your choice No. 1 when you need to do a survey in a very rough terrain or when the speed of the survey is paramount.

Area of applications: Rough and uneven terrain where ground coupled antennas cannot be used. Secondary lining tunnel surveys. Ballast inspection surveys. Snow layer measurements from helicopters. Volcanic ash layer measurements from helicopters. High speed road inspection surveys.
