COMPACtenna Optimized Compact HI Performance Ham Radio Antenna 2Meter&440 Bands

Description

COMPACtenna Optimized Compact High Performance 2 Meter + 440 Bands
Only 7.5” long. Made is the USA.  Each antenna quality tested.
Reliable leaf spring style NMO connector on antenna for standard center-stud style NMO mounts
See separate listing for NMO magnetic mount & also packaged listing of this antenna & magnet mount (sold together).
Antenna Type:
Unique Electric/Magnetic Field Diversity Science & Technology Patented Design.  Patent No. US 9,407001.
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 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, under overhangs, 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)]
(V)SWR: Nominal <2:1 144-148 MHz; 430-450 MHz
(
V)SWR’s can vary with size and shape of vehicle and vehicle accessories.
Best (V)SWR’s on VHF frequencies are generally seen when mounting at upper corners of the 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 Station antenna with a Base Station Conversion Kit.
(See separate listing for Base Station Conversion Kit).
**For best SWR & performance (when using Base Station Conversion Kit)  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.
