Linq 6ghz 2FT (642mm) Dual Polarized / Slant ±45 30dBi Parabolic Dish Antenna (2 Pack)

The LinQ Antenna Technology LD5168DP2-2PK is a two-pack of high-performance 30 dBi dual-polarized parabolic dish antennas designed for long-range point-to-point wireless links operating from 5.15 to 6.875 GHz.

Each LD5168DP2 features a 642 mm (25.3 in.) reflector, dual RF ports, and support for either horizontal/vertical or ±45° slant polarization. The wide operating bandwidth allows a single antenna platform to support traditional 5 GHz wireless systems as well as newer 6 GHz equipment operating through U-NII-7.

With narrow beamwidth, high front-to-back rejection, and strong port isolation, the LD5168DP2 is designed to maximize signal-to-noise ratio while minimizing interference from adjacent and co-located wireless systems. The two-pack configuration provides a matched antenna pair suitable for both ends of a high-capacity point-to-point wireless link.

Wideband 5 GHz and 6 GHz Performance
The LD5168DP2 operates continuously from 5.15–6.875 GHz, covering frequencies from U-NII-1 through U-NII-7. Gain increases across the operating band, ranging from approximately 27.3 dBi at the lower end of the 5 GHz band to 30.5 dBi at the upper end.

This wideband performance makes the antenna an excellent choice for network operators who need flexibility when selecting channels or transitioning between 5 GHz and 6 GHz radio platforms.

Narrow Beamwidth for Long-Range Links
The antenna's narrow radiation pattern concentrates RF energy toward the remote site, improving link budget while helping reject unwanted interference.

Depending on operating frequency, the horizontal -3 dB beamwidth ranges from approximately 6.0° at 5.15 GHz to 4.3° at 6.875 GHz. A typical 40 dB front-to-back ratio further improves isolation from signals originating behind the antenna.
