COMPACtenna "LMR-1" RADIO ANTENNA- BUSINESS-COMMERCIAL-SAFETY 2 WAY

Description

** NOTE** THIS ANTENNA IS SPECIAL ORDER & THERE IS A 7 BUSINESS DAY LEAD TIME FROM DATE OF PURCHASE UNTIL ANTENNA(S) ARE SHIPPED.
COMPACtenna "LMR - 1" High Performance Antenna - Made in USA;
for Commercial-Business-Safety Two-Way LMR Radio Communications
Only 9" long.
Reliable leaf spring style NMO connector on antenna for standard center-stud style NMO mounts.
Optimized for 3 Wide Frequency Bands;
VHF 136 - 174 MHz
UHF 378 - 512 MHz
750 - 960 MHz
Digital & Analog
Business - Commercial - Public Safety
High Performance low profile vehicle antenna
Also excellent for Base Station / Repeater use particularly with installations below 100-150' above ground / HAAT - where non-line of sight (NLOS) propagation is more substantial
Antenna type:  Unique Electric/Magnetic Field Diversity Science & Technology Patented Design.
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 with movement & location changes such as behind building, in garages, behind other vehicles, and in valleys.
Maximum Power Ratings
Vehicle & Base Station Operations: 100 Watts VHF; 75 Watts at higher frequencies
Maximum Duty Cycle at max. power ration: Maximum total transmit time of 1 minute in any 2 minute period
Repeater Operation: 30 Watts at the antenna (e.g., 45watt transmitter with 2dB feedline loss), all Frequency Bands
Maximum Ambient temperature rating 130 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<2:1 140-162MHz, 400-500MHz, 750-960MHz
<2.5:1  136-140MHz, 162-174MHz, 378-400MHz, 500-512MHz
Best (V)SWR's on VHF frequencies are generally seen when mounting at corners of a vehicle.
Signal pattern is substantially omnidirectional at corner locations.
(V)SWR's can vary with size and shape of vehicle & accessories.
(V)SWR's seen by the radio are often lower due to coaxial/feed-line attenuation.
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/repeater antenna
by utilizing the COMPACtenna CompacCounterpoise, a heavy duty ground plane counterpoise optimized
for both SWR and pattern on VHF & UHF frequencies; (V)SWR: nominal <2:1 144-162MHz, 430-470MHz.
** COMPACtenna CompacCounterpoise will be listed as soon as available.**
Also see my current listing for a durable base station adapter kit.
Each antenna quality tested
Use lube provided for NMO threads and gasket, tighten securely; do not use on center contacts.
