COMPACtenna 2M/440

Optimized Compact High Performance 2 Meter + 440 Bands

• Only 7.5" long
• Reliable leaf spring style NMO connector on antenna for standard center-stud style NMO mounts

• Superior Science Performance with Vehicle Location Changes and Movement
• Superior Science Performance in NLOS (Non-Line-Of-Sight) Obstructed Environments such as behind buildings, in garages, behind other vehicles, under overhangs, and in valleys

System Applications:

• Digital & Analog VHF Amateur (HAM) Radio
• Digital & Analog UHF Amateur (HAM) Radio

• [Duty Cycle at max. power rating: Maximum total transmit time of 1 minute in any 3 minute period. Hotter conditions such as higher ambient temperature, sun exposure, lesser air flow, etc. decrease duty cycle.]

• [Performance is greater than predicted based on gain alone in NLOS (Non-Line-Of-Sight) environments which is the world we live in.]

• (V)SWR’s can vary with size and shape of vehicle and vehicle panels.
• Best (V)SWR on VHF frequencies are generally seen when mounting at corners of the vehicle roof/trunk-lid/quarter panel; on a bracket mount; on a (light) bar. Signal pattern is substantially omnidirectional with these mounting options.
