The Retevis Ailunce AY04 High Gain Antenna (HGA) is a 2-band directional antenna with a simple aluminium construction. High-gain antennas provide a more precise way to target radio signals and are therefore very important for long-range wireless networks. They also amplify weak signals used in satellite communications.
All ends of the elements and traverses are closed with plastic caps.
All holes and elements of the antenna are numbered, which simplifies assembly.
