Technical Specifications of Horn Antenna 55-200 4.8-5.9 GHz

The Horn Antenna 55-200 is a directional horn antenna 4.8-5.9 GHz designed for UAV video link horn antenna 4.8-5.9 GHz applications, FPV video channel systems, and repeater / relay horn antenna for UAV video link tasks. This 4800-5900 MHz RHCP horn antenna operates across the 4.8-5.9 GHz range and has a 5.35 GHz center frequency, making it suitable for stable signal transmission and reception in airborne video links.

As a 4.8-5.9 GHz horn antenna 18 dBi, it combines high directivity horn antenna performance with RHCP / right-hand circular polarization. The antenna uses 1× SMA-Female horn antenna 50 Ohm configuration, supports up to 50 W RF power handling, and maintains VSWR 1.5 in the operating band. Rear radiation suppression is specified at < -40 dB, while the approximate -3 dB beamwidth is ~12° (H) × ~12° (V).

Key Features of Horn Antenna 55-200 18 dBi

Directional horn antenna 4.8-5.9 GHz for focused RF transmission

This directional horn antenna 4.8-5.9 GHz is built for focused signal transmission and reception in UAV and FPV video channels. The narrow beam pattern of approximately 12° × 12° helps direct RF energy toward the intended path.

High-gain horn antenna 18 dBi

The antenna provides 18 dBi gain at 4.9 GHz, which supports stable communication in video link systems where a focused signal path is required.

Circularly polarized horn antenna (RHCP)

With RHCP / right-hand circular polarization, this FPV horn antenna RHCP configuration is intended for UAV video link and FPV video transmission antenna RHCP use. The product information also states lower dependence on antenna orientation.

Low VSWR and good impedance matching

This low VSWR horn antenna has VSWR 1.5 in the working band and a 50 Ohm input impedance. As a good impedance matching 50 Ohm horn antenna, it is intended for properly matched RF link systems in the 4.8-5.9 GHz range.

Rear radiation suppression < -40 dB

Rear radiation suppression < -40 dB helps reduce unwanted radiation behind the antenna. Together with the horn design, this supports cleaner directional performance for UAV video link antenna 5.8 GHz and 4.8-5.9 GHz applications.

Aluminum construction and lightweight form

The antenna is made of aluminum and has dimensions of 300 × 300 × 250 mm with an approximate weight of 180 g. It is specified for UAV wing mount installation.

Applications

UAV and FPV video links

This UAV video link horn antenna 4.8-5.9 GHz is intended for video channels of unmanned aerial vehicles, including FPV and related airborne video transmission systems.

Repeater / relay use

The product is specified for repeater (relay) use, which makes it relevant as a repeater / relay horn antenna for UAV video link configurations.

5.8 GHz band RHCP horn antenna tasks

Within its full 4.8-5.9 GHz range, the antenna can be used in 5.8 GHz band RHCP horn antenna applications where directional transmission and reception are required.

Drone video channel antenna 4.8-5.9 GHz

This model is suitable for drone video channel antenna 4.8-5.9 GHz tasks, FPV video channel horn antenna 5.8 GHz RHCP setups, and RF link antenna 4.8-5.9 GHz systems that use directional circular polarization.

Compatibility of Horn Antenna RHCP Circular Polarization

System compatibility

The antenna is intended for UAV/FPV video links and repeater applications operating in the 4.8-5.9 GHz / 4800-5900 MHz range. It is specified with a 1× SMA-Female connector and 50 Ohm impedance, so it should be used in RF systems designed for these parameters.

Mechanical compatibility

The specified mounting method is UAV wing mount. This makes the antenna suitable for aircraft installations where wing mounting is required by the system design.

Polarization options

The standard version uses RHCP / right-hand circular polarization. LHCP is optional on request.

How It Works❓

A horn antenna creates a focused directional beam by guiding RF energy through its horn structure. In this model, the approximate 12° × 12° beamwidth concentrates signal energy for stable UAV/FPV video links in the 4.8-5.9 GHz range, while RHCP polarization supports reliable transmission and reception with lower sensitivity to antenna orientation.

Why Choose the Horn Antenna 55-200 4.8-5.9 GHz, 18 dBi, RHCP Circular Polarization, 1×SMA-Female, 50 Ohm❓

👉Choose this antenna when you need an 18 dBi directional 4.8-5.9 GHz RHCP horn with VSWR 1.5, rear radiation < -40 dB, 50 W power handling, and a 1×SMA-Female 50 Ohm configuration for stable UAV/FPV video links, repeater tasks, and long-range airborne communication.
