COMPACtenna 2M/220/440 Optimized Compact High Performance HAM Radio Antenna 7.5"

Description

COMPACtenna  MODEL:  2M/220/440.  MADE IN USA.
New, Unused Antenna.  Each Antenna quality tested.
Optimized Compact High Performance HAM Radio 2 Meter + 220 + 440 Bands.
Only 7.5" long.
Reliable leaf spring style NMO connector on antenna for standard center-stud style NMO mounts.
Proper NMO magnet mount sold in separate listing. Also, this antenna & magnet mount sold as package in separate listing.
Antenna type:  Unique Electric/ Magnetic Field Diversity Science & Technology Patented Design. Patent No. US 9,407,001
With a special design construct of spiraled & 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 resonation 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 obstructions,
mitigating signal drops, reducing flutter, and increasing reliable range.
Small Rugged Antenna with High Performance.
Superior Science Performance with Vehicle Location Changes & Movement.
Superior Science Performance in NLOS (non-line-of-sight) Obstructed Enviroments such as behind buildings,
in garages, behind other vehicles, under overhangs, and in valleys.
Digital & Analog VHF Amateur (HAM) Radio
Digital & Analog 220 Band Amateur (HAM) Radio
Digital & Analog UHF Amateur (HAM) Radio
Max Power Rating: 85 Watts 2 Meter Band; 30 Watts 220 Band;  50 Watts 440 Band.
(Maximum Duty Cycle at max. power rating; Maximum total transmit 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 environments, which is the world we live in.)
(V) SWR: Nominal < 2:1  144-148 MHz;  222-225 MHz;  430-450 MHz
(V) SWR's can vary with size and shape of vehicle and accessories.
Best (V) SWR's on VHF frequencies are generally seen when mounting at upper corners of a vehicle.
Signal pattern is substantially omnidirectional with these mounting options.
Always check SWR: operate only per transmitter/amplifier specifications.
Base Station Antenna:  This revolutionary antenna may also be used as a High Performance Compact Base
antenna with our base ground conversion kit, (see separate listing).  For best SWR & performance angle (bend)
the ground plane radials downward 45 degrees below the horizon.
Use lube provided for NMO threads and gasket, tighten securely, do not use on center contacts.
