Arkbird High Gain Directional Panel 1.2g 1.3g 1.2GHz 1.3GHz FPV Cross Antenna-10 DB for 1.2g transmitter and receiver long range
ARKBIRD-1.2GHz/1.3GHz Cross Antenna is a 10dbic directional antenna attributed by exceptionally high axial ratio reaching 0.98, and SWR less than 1.1. Such antenna can properly match requirement in definite environment of broadcasting long-distance signal which is receivable in particular range and amongst objects.
This Antenna is made for FPV equipment, prefectly suitable for most of AAT in the market.
I. ARKBIRD1.2GHz/1.3GHz Antenna Basic Parameters
Axial Ratio: 0 .98
Beam width: 115 degrees
-3db point: +/- 35 degrees
Polarization: Right Hand Circular (RHCP) or Left Hand Circular(LHCP)
(1). Materials: thickened aluminum sheet, imported materials for core components, high-precision machine cut. Size error of artificial work is about 1.5mm. But size error of Arkbird Antenna made by machine is within 0.1mm.
(2). Simulation and test: all designs have been simulated by computer software. And each antenna has been passed test by professional network analyzer before delivery.
PS: these high gain antennas have a long transmission distance, while they have strong requirement on the correct signal direction; work with Arkbird AAT is a good choice.
(3) Material selection and design optimization: the final outline, materials and feeder have passed more than 10 times of test and they are the best one selected from available supplies.
(4) Standing-wave ratio: it can match the receive port of 50R. The SWR of antenna of Arkbird is less than 1.1.So the efficiency can be ensured at the highest-level. Besides, SWR of most other antennas are just less than 1.7 only.
(5)Arkbird 1.2G antenna design have been passed distance extension test. We find that working distance of Arkbird antenna is 3 times to 6 times that of rod antenna. While being powered by single transmitter which output is 500mW, the extension distance of rod antenna is about 800m and the extension distance of Arkbird 10DB directional antenna is over 3km under the same occasion.
(6)After several testing, we finally get image from 53 kilometer at the height of 1km with the help of this 1.2GHz Antenna and AAT, Besides, 2W transmitter is needed.
Back part of cross antenna, which has a screw allows it to be easily mounted on a tripod or Arkbird AAT:
