Terry Pinwheel antenna Build 5.8GHz SL SMA 90°
NEW: the connector is bended at 90° allowing a better orientation toward the ground
These antennas, circularly polarized, re the first on the the market to be certified with a VSWR less than 1.5. The SWR is a measure of the power radiated by the antenna: with an VSWR of 1.5 you have 96% of the emission taht is radiated by the antenna. The more you get closer to 1 the better your antenna is.
1001 Copters has commissioned France IP company to validate the measures performed by antenna's manufacturer. The measurement datsheet is available in the document section.
(These curves represents the test of one antenna randomly picked)
The circular polarization of these antennas make them particularly insensitive to interference caused by the environment. They must be used either in pairs or with a patch antenna 9/12db (the stick antenna with 3db gain are not suitable because of their linear polarization, we loose all the gain of the antenna stick by mixing circular polarization and linear polarization)
it is mounted on semi-rigid coaxial cable that allows professional orientation and retention in the position best suited to your own installation. It is recommended to tilt / manipulate the antenna cable and connector and not the lobes.
His opposition to the polarization direction or axial ratio is greater à13dB allowing it to be very sensitive to different wave reflections in the environment and ensures the stability of the transmission of the millimeter wave band 5.8 Ghz very sensitive these phenomena.
-Type RHCP/50 Ohm / omni
Semi-rigid coaxial cable-18GHz (adjustable at leisure)
-Gain 2dB theoretical means: perfect homogeneity of the radiation (unlike antennas 3 lobes)
-Lobes in unique materials: the diameter of circular section for optimum 5.8Ghz hardened steel (strength, elasticity, shape memory), copper (industrial grade, optimum conductivity), anti flaking varnish (protects from oxidation, maintaining appearance).
-Solder tin / silver for high frequencies. (Re weldable rupture after a crash)
-Range: 200mw ~ 2km
Rate-Stationary Wave (TOS) warranty <1:1.2 (more than 99% of the power radiated by the antenna), individual measurement bench. (Return loss (RL)> 20dB)
-Taking the wind negligible.
-Available in SMA.
-Weight: 3,7 gr /
Content: 5.8 GHz antenna SMA connector
