RF-1940

® assuredcommunications™ RF-1941/ RF-1940 SERIES HF MANPACK, PORTABLE DIPOLE ANTENNA The RF-1941/RF-1940 Series are lightweight, portable dipole antennas designed for use in the 2 to 30 MHz range with a maximum power of 500 Watts. The antenna is stored on selfcontained flat spools, which form an integral part of the antenna. During operation, unwind to frequency marker and deploy; the unused portion remains on the storage spool. Each spool also contains throwing line that can be connected to masts, trees, buildings, poles, etc. The RF-1941/RF-1940 Antenna series can be connected directly to the AN/PRC-138, AN/PRC-150, or RF-5800H manpack, using the manpack’s built-in antenna coupler for ALE operation. The antenna design can be configured as a dipole, sloping dipole, sloping V, or as a vertical rhombic antenna depending on support and terminations (none are supplied). It includes a 10-meter, 50Ω coaxial cable with BNC male connectors. A BNC-to-Type N adapter is also included. The RF-1941 is completely contained in a heavy duty 6" x 12" x 3" OD bag with strap and clip points to attach to a military ruckpack. The RF-1941 is more rugged than the low cost RF-1940. Specifications for the RF-1941 / RF-1940 Series Electrical I Frequency Range 2.0 to 30 MHz (RF-1941) 3.0 to 30 MHz (RF-1940) I RF Power Capacity 500 Watts (2.0 MHz to 30 MHz) I Input Impedance 50 ohms (nominal) I Radiation Pattern See below I Polarization Horizontal (Dipole Configuration) I VSWR
