Antenna, Biconical Omnidirectional, 0.3–8 GHz, 5 dBi, 50 Ohm, N-female
0.3-8 GHz Biconical Omnidirectional Antenna for Radio Monitoring, RF Measurements, and Telecommunication Systems
The 0.3-8 GHz broadband omnidirectional biconical antenna is a professional RF antenna for receiving and transmitting radio frequency signals in an ultra-wide range from 300 MHz to 8000 MHz. The antenna is suitable for radio monitoring, spectrum analysis, laboratory and field measurements, telecommunication systems, test benches, and other tasks requiring broadband omnidirectional coverage.
Thanks to its biconical design, the antenna provides stable operation across a wide frequency range without the need for multiple separate narrowband antennas. The 360° circular radiation pattern in the horizontal plane allows for receiving or transmitting signals from all azimuthal directions without mechanical antenna rotation.
The model has a characteristic impedance of 50 Ohm, vertical linear polarization, an N-female RF connector, and a gain of up to 5 dBi. Its all-weather design with IP65 / IP66 protection class allows the antenna to be used both indoors and outdoors.
Purpose of the 0.3-8 GHz Biconical Antenna
- Radio monitoring in the 300-8000 MHz range. The antenna is suitable for controlling the radio frequency spectrum, detecting active signals, and analyzing the electromagnetic environment.
- RF measurements and spectrum analysis. Can be used with spectrum analyzers, receivers, measurement systems, and laboratory equipment.
- Telecommunication and test systems. The antenna is suitable for use in transceiver paths, test benches, antenna systems, and signal control systems.

Materials and Construction
- Biconical Radiator. The internal antenna element has a biconical shape, ensuring broadband operation and stable parameters in the 0.3-8 GHz range.
- Radio-transparent Protective Housing. The outer radome is made of a polymer material resistant to UV radiation, mechanical stress, and weather conditions.
- Solid Metal Base. The rigid base secures the antenna structure, protects the connection point, and ensures reliability during installation.
- N-female RF Connector. The N-type coaxial interface ensures compatibility with common RF cables, adapters, and measurement equipment.
- Mounting Kit. Fasteners allow the antenna to be installed on a pipe or mast of appropriate diameter.
Functionality
The biconical antenna supports operation in an ultra-wide frequency range from 300 MHz to 8 GHz, allowing it to be used for a wide range of RF tasks without frequent antenna equipment changes.
The circular radiation pattern in the horizontal plane provides uniform 360° coverage. This is convenient for radio monitoring, panoramic spectrum analysis, and receiving signals from various directions without changing the antenna's position.
Vertical linear polarization, 50 Ohm characteristic impedance, and an N-female connector make the antenna compatible with most professional RF equipment, including spectrum analyzers, receivers, signal generators, amplifiers, and transceiver modules.
Compatibility
- Compatibility with spectrum analyzers. The antenna can be used with equipment from Rohde & Schwarz, Keysight, Rigol, Signal Hound, and other devices with the appropriate frequency range and 50 Ohm input.
- Compatibility with RF receivers and transmitters. Suitable for use with radio frequency devices that have a nominal characteristic impedance of 50 Ohm.
- Compatibility with coaxial cables. Cable assemblies with N-male connectors, including those based on RG-213, LMR-400, and similar models, can be used for connection.
- Compatibility with mounting systems. The antenna can be installed on masts, pipes, brackets, and other vertical supports of appropriate diameter.
Advantages of the Biconical Omnidirectional Antenna
- Wide range 0.3-8 GHz. One antenna covers a significant portion of the radio frequency spectrum and can replace several narrowband antennas in many tasks.
- 360° omnidirectional coverage. The circular pattern in the horizontal plane allows working with signals from various directions without mechanical rotation.
- Gain up to 5 dBi. The antenna provides sufficient gain for monitoring, measurements, and working with radio frequency paths.
- All-weather IP65 / IP66 design. The protected housing allows the antenna to be used outdoors.
- Standard N-female interface. The N-type connector simplifies connection to cable assemblies, measuring instruments, and RF equipment.
- Compact and rigid design. Dimensions Ø310×200 mm and weight approximately 1.8 kg facilitate transportation, installation, and use in mobile or stationary systems.
