AKK 5.8GHz 6dBi Diamond Antenna RHCP SMA (160mm)

The AKK Diamond is a 160mm, 5.8GHz RHCP omnidirectional antenna with an SMA connector, built as a higher-gain replacement for the stubby and rubber-duck antennas bundled with analog video transmitters. AKK designed it for its Alpha 4, Alpha 5, Alpha 8, Alpha 10 and Ultra Long Range All Channels VTX, and it suits any 5.8GHz VTX or video receiver with an SMA socket.

Key features

• Up to 6dBi gain: 4.5-6dBi across the band for more range and penetration than stock stubs.

• RHCP polarisation: rejects reflected signals, reducing multipath breakup during fast, low flying.

• Omnidirectional pattern: 360° coverage, so the signal holds whichever way the quad faces.

• Efficient match: VSWR below 1.8 at 50 ohm across 5.5-6GHz.

• 50W power rating: ample headroom for high-power VTX output.

Run the same polarisation at both ends: pair it with RHCP antennas on your goggles or video receiver, as a mismatched LHCP link loses a large share of its range.
