Antenna iFlight Crystal LHCP Patch 5.8GHz Directional

iFlight Crystal Patch Antenna is a directional high-gain antenna designed to provide better long-range reception and superior penetration through trees, obstacles, and difficult terrain. Its low-profile design minimizes packaging size, while high-quality RG178 cables ensure maximum durability. A ultra-wide beamwidth is achieved thanks to a 30-degree angle offset between the two elements, delivering a 105-degree horizontal beam and a 75-degree vertical beam at 9 dBi gain, which decreases gradually toward the sides. It features low losses with a 93% antenna efficiency and an axial ratio of ≤1.6 across the entire band. Additionally, it offers the flexibility to be installed on either the top or bottom pair of the Goggles' RP-SMA connectors. Multiple design options are available.

Features

Available in 3 design options: black carbon, blue sticker bomb, and red/yellow color bomb.
