This new antenna from the SL series offers more performance : with one additional lobe (5 in total, against 4 for the classic pinwheel), you get even more transmission range and quality. 

The TerryBuild SL is the last evolution of the PinWheel 5.8Ghz MK2, a circular polarization antenna optimized for the FPV flight.
It offers a great transmission quality and reliability which was never matched by other type of antennas (like dipole, Yagi, patch etc...)

The SWR of this antenna is lower than 1.2 which means that over 99.2% of the transmitter's power is radiated by the antenna.

This antenna covers all the channels in 5.8GHz with a VSWR lower than 1.5.

The lobes are made in steel and covered by 0.5mm of copper, in order to have a good rigidity and strengthens while keeping the copper's conductive performance.

Mounted on an orientable professionnal coaxial cable with an SMA male connector, this antenna can be easily oriented and measures only 7cm of height and has a diameter of 3.5cm.

To take advantage of these antennas, you need 2 of them:

• one on the transmitter
• the other on the receiver

• Frequency: 5.8GHz
• Channels: 5645-5945MHz
• Gain: <2.4dB
• Impedance: 50 Ohms
• Angle: 360°
• SWR: < 1:1,2
• Connector: RP-SMA angled at 90°
• Height: 6 cm
• Diameter: 3,5 cm
• Weight (approx): 3.7 gr

• 1 Antenna
• 1 Tightening gear for the connector
• 1 Top protection
