Compact UHF transmit/receive antenna for naval applications

The R&S®AD033V3 is an omnidirectional UHF antenna system for naval applications, covering the frequency range from 225 MHz to 450 MHz. The antenna can be used for transmit and/or receive purposes. Circularly arranged dipoles around the center support structure are combined to one output, resulting in excellent omnidirectional behavior. The antenna is designed for simultaneous use by several independent transmitters.

Features & benefits

Excellent omnidirectionality

For undisrupted communications

The R&S®AD033V3 has eight vertically polarized dipoles arranged in a circle in front of a reflector. The individual dipoles are combined to one output with excellent omnidirectionality. The whole antenna is arranged around a central mast, enabling uninterrupted omnidirectional communications.

High input power

For simultaneous use of multiple radio lines

The R&S®AD033V3 omnidirectional UHF antenna is designed to handle high input power, enabling a series of individual transmitters to simultaneously connect to a single antenna. This reduces the space needed compared with the conventional design using one antenna for each radio and also helps avoid the typical interference between antennas.

Stackable antenna design

For easy mounting and retrofitting

The R&S®AD033V3 is designed as a wrap-around antenna for masts. The antenna has excellent omnidirectional behavior. As RX and TX paths are sometimes separated, a second antenna is required. The AD033V3 is stackable, making it easy to mount additional antennas.

Reduced RCS

For better protection

The shape of the R&S®AD033V3 has been optimized during the design phase, which is important for the electrical behavior of the antenna, e.g. its radiation pattern. The antenna shape also determines the radar cross section (RCS). For deployment on naval vessels, the RCS must be as low as possible.

DC grounding for lightning strike protection

For protecting personnel and equipment

All metallic parts of the R&S®AD033V3 are DC grounded to direct potential overvoltage surges such as lightning strikes into the ground, protecting personnel and connected equipment.
