COMPACtenna Tri-Band Antenna (2M/220/440) with LAIRD Magnetic Mount

COMPACtenna 2M/220/440 Tri-Band Antenna with LAIRD (GBR8PI) Magnetic Mount Bundle! Optimized Compact High Performance HAM Radio Antenna for 2 Meter + 220 + 440 Bands. 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. 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 E & H fields production, resulting in better performance than expected for such a small antenna.

With a particularly strong magnetic near field, proximity noise is reduced. 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. Digital & Analog VHF Amateur (HAM) Radio. Digital & Analog 220 Band Amateur (HAM) Radio. Digital & Analog UHF Amateur (HAM) Radio.

Broad elevation coordinate signal pattern and elliptical polarization of COMPACtenna provides stabilized signals in our common Non Line of Sight environments, with temperature and humidity inversion pathways as well as tropospheric propagation, and SATELLITE communications. Maximum Duty Cycle at max. Hotter conditions such as higher ambient temperature, sun exposure, lesser air flow, etc.

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.

LAIRD 3 1/8 MAGNETIC MOUNT (GBR8PI) WITH 12' RG58AU COAX & PL-259 CONNECTOR (PLUG). Best (V)SWR's especially on VHF frequencies are generally seen when mounting at upper corners of a vehicle. Signal pattern is substantially omnidirectional at corner locations.

(V)SWR's can vary with size and shape of vehicle and 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 antenna by utilizing a base station adapter kit. See my separate listing for a COMPACtenna COUNTERPOISE Bundle! Listing is for antenna & magnetic mount only. Use Lube provided for NMO threads and gasket, hand tighten securely; do not use on center contacts.
