COMPACtenna 2M/220/440 Amateur Radio Antenna & CompaCounterpoise BUNDLE

Optimized Compact High Performance HAM Radio Antenna for 2 Meter + 220 + 440 Bands & CompacCounterpoise Heavy. Duty Ground Plane Counterpoise for VHF & UHF BUNDLE!!

Antenna: Only 7.5 long. 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. 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. If a magnet mount is used, the'Flat' style often provides best SWR's.

(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. See my separate listing for this antenna & Workman 3 magnetic mount bundle.

Base Station antenna: The CompacCounterpoise heavy duty ground plane radial kit optimized for gain, pattern &. SWR on VHF & UHF for COMPACtenna models.

Excellent for Base Station/ Repeater use particularly with installations below 100-150' above ground/ HAAT. Where non-line-of-sight propagation is more substantial.

Easy installation, much of unit is pre-assembled. 18" elements to 3" diameter plate attachment; elements optimally angled in factory at 45 degrees below. Plate has NMO mount above.

Stainless steel hose clamps provided allow for 1 1/4"- 1 3/4" OD mast/pipe. Maximum Power Ratings: 200 Watts up to 225 MHz, 100 Watts at higher frequencies.
