COMPACtenna Model: Scan III (9) Antenna. Ompact High Performance SCANNER RADIO Antenna. Particularly superb on 3 Wide Frequency Bands. VHF 136 - 174 MHz.
UHF 378 - 512 MHz. Digital & Analog - Including Public Service-Safety/Govt Frequency Bands. 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 far fields further enhance performance in our world of (dynamic) obstructions. Mitigating signal drops, reducing flutter, and increasing reliable range. 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. Reliable leaf spring style NMO connector on antenna for standard center-stud style NMO mounts. Gain: Nominal 3(+) dBi. Due to properties listed above, performance is greater than predicted based on gain alone in NLOS (Non-Line-Of-Sight) environments. Which is the world we live in.
The COMPACtenna CompacCounterpoise, (SEE PHOTO) a heavy duty ground plane counterpoise radial kit optimized for both SWR and pattern. On VHF and UHF frequencies. See separate listing for COMPACtenna CompacCounterpoise. Use Lube provided for NMO threads and gasket, tighten securely; do not use on center contacts.Some photos for example purposes only. Listing is for Scan III Antenna ONLY. Item located in zip code 44094.
