COMPACtenna 7.5in High Performance HAM 2M/440 Antenna
Optimized Compact High Performance HAM Radio Antenna for 2 Meter + 440 Bands Only 7.5” long Reliable leaf spring style NMO connector on antenna for standard center-stud style NMO mounts
Antenna Type: Unique Electric/Magnetic Field Diversity Science & Technology Patented Design Patent No. US 9,407,001
With a special design construct of spiraled and cylindrical metal sheeting including ‘extended flat monofilar spiral Tesla-like coils’, all resistance, inductance and capacitance (matching) is efficiently done by the physical metallic geometric form of the antenna itself, as opposed to internal or external (lossy) components of other designs.
“Magnetic Field Resonator”: This built-in resonating matching system is an effectual component of the electromagnetic field production, resulting in better performance than expected for such a small antenna.
And resulting diverse effective electromagnetic fields further enhance performance in our world of (dynamic) obstructions, mitigating signal drops, reducing flutter, and increasing reliable range.
Product Narrative: Small Rugged Antenna with High Performance 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, and in valleys
System Applications: Digital & Analog VHF Amateur (HAM) Radio Digital & Analog UHF Amateur (HAM) Radio Maximum Power Rating: 85 Watts 2 Meter Band; 50 Watts 440 Band [Maximum Duty Cycle at max. power rating: Maximum total transmit time of 1 minute in any 2 minute period.
Maximum Ambient temperature rating 110 degrees Fahrenheit. Hotter conditions such as higher ambient temperature, sun exposure, lesser air flow, etc. decrease duty cycle.]
Gain: Nominal 3(+) dBi [Performance is greater than predicted based on gain alone in NLOS (Non-Line-Of-Sight) environments which is the world we live in.]
