PERFORMANCE AND DESIGN
The RADIOHUB RHU-10 is designed with a 10-element directional configuration to provide focused UHF signal transmission and reception. The directional radiation pattern helps concentrate the antenna performance toward the desired communication direction while reducing unwanted signals from other directions.
The antenna operates within the 434–440 MHz frequency range and is suitable for applications requiring reliable directional UHF coverage. Proper installation and antenna alignment are important for achieving the best possible communication performance.
The simulated radiation characteristics show a maximum gain of up to 18.06 dBi. The antenna also provides a Front-to-Back Ratio of approximately 30.32 dB, helping reduce signals and interference received from the rear direction.
DIRECTIONAL PERFORMANCE
The RHU-10 features a focused directional radiation pattern with a simulated -3 dB beamwidth of approximately 40.6 degrees. This directional characteristic makes the antenna suitable for applications where concentrated RF coverage is required.
The maximum radiation direction is at approximately 0 degrees in the simulated azimuth pattern. The sidelobe gain is approximately -0.77 dBi, while the Front-to-Sidelobe Ratio is approximately 18.83 dB.
These characteristics can help provide improved signal directionality when the antenna is correctly installed and aligned toward the intended communication location.
INSTALLATION RECOMMENDATIONS
For best performance, install the RHU-10 antenna at a suitable height with a clear surrounding area. Avoid installing the antenna close to large metal structures, electrical equipment or other objects that may affect its radiation pattern.
The antenna should be mounted securely using a suitable mast and mounting arrangement. The boom should be aligned carefully toward the required communication direction.
A good-quality 50 Ohm coaxial cable should be used to connect the antenna to the radio equipment. Keep the coaxial cable length as practical for the installation and ensure all connectors are properly tightened.
For outdoor installations, RF connectors and cable joints should be protected against moisture and weather exposure. Proper grounding and lightning protection should be considered according to the installation environment and applicable electrical safety practices.
APPLICATION PERFORMANCE
The RHU-10 is suitable for amateur radio operators, repeater systems, fixed communication stations and experimental RF applications operating within its intended frequency range.
Its directional design makes it particularly useful where communication is required in a specific direction rather than providing equal coverage in all directions. This can be useful for point-to-point communication links, signal monitoring and directional receiving applications.
The final communication performance depends on several factors including antenna installation height, surrounding terrain, obstacles, coaxial cable quality, connector condition, transmitter power and receiver sensitivity.
