RF-3191-AT001

® assuredcommunications™ RF-3191-AT001 RAPIDLY DEPLOYABLE VHF ANTENNA The RF-3191-AT001 is a transportable omnidirectional antenna specifically designed for quick deployment and ease of operation. A unique tripod leg structure allows the antenna to be mounted directly over the ground or mounted on a standard communications mast. The antenna covers 30 to 90 MHz frequency band with optimized passive tuning. The RF-3191 enables rapid deployment (less than a minute) due to its sophisticated tripod design and can be disassembled and stowed just as quickly. The RF-3191 consists of the main antenna body, thin extender element, three legs, coaxial cable, adapters, and carry bag. The tripod legs collapse and can be either removed or rotated parallel to the lower radiating section. The entire assembly stows in a volume of less than 36" long by 10" diameter and contained within a carry bag. When increased range is required, the RF-3161 can attach to a mast via a 3/4”-10 threaded hole in the antenna body. This is the typical mast mount found on many masts such as the OE254 mast. Additionally, an optional adapter can be provided for clamp mounting to a mast with a 1.5" diameter top section. For fixed installations, the telescoping legs can be replaced with metallic ground radials that connect directly to the guy wires. Specifications for the RF-3191-AT001 Electrical I Frequency Range 30 to 90 MHz, usable up to 108 MHz I Gain See Below I VSWR 3.0:1 (see below) I Input Impedance 50 Ohms (nominal) I RF Power 200 W Average I Polarization Vertical I Radiation Pattern Omnidirectional Mechanical I Element Height 68 Inches (1.7m) I Element Diameter Antenna Body 3.0 Inches (0.076m) Extender Element 1.5 Inches (0.038m) I Deployed Height 105 Inches (2.7m) I Stowed Size 36" x 10" Dia.
