5.8GHz high gain circularly polarized directional antenna Technical indicators: 1. Frequency bandwidth: 5GHZ-6GHz 2. Polarization method: circularly polarized antenna (left-hand) 3. Impedance: 50Ω 4. Gain:13.8dBi 5. Radiation angle: 42° 6. Standing wave ratio: (5.5GHZ-6GHz) less than 1.2 7. Maximum power: 50W 8. Connector type: internal needle (left-handed) Colour:black Material:Metal important : Because the gain of this antenna is too high, although the radiation angle of the pattern is narrow, it is suitable for long-distance communication. If the short-range communication requires the transmitter antenna and the receiver antenna to be aligned, the communication effect not be achieved if the antenna deviates from the radiation range. Suitable for long-distance travel machine image transmission remote control, eyes. Note: Installation guide not included, we strongly recommend you professional installation. Please check as much as possible to make sure the item is what you need. Due to different product batches, the appearance , which does not affect the use Package Contents: 1 * internal needle (left-handed) Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
