In RF testing and microwave measurement, choosing the right antenna can directly affect both efficiency and accuracy. For engineers working in EMI testing, antenna pattern measurement, gain verification, or surveillance-related applications, a stable and broadband conical horn antenna is often a practical and dependable option. RF MISO offers two well-designed models for these needs: the RM-CHA90-15 and the RM-CHA159-15.
The RM-CHA90-15 is a conical horn antenna operating from 8 to 12 GHz. It provides a typical gain of 15 dBi and a typical VSWR of 1.3:1, making it a solid choice for high-frequency microwave applications that require good impedance matching and consistent radiation performance. Its frequency coverage makes it suitable for a wide range of laboratory, field, and system integration tasks where directional performance is important.

The RM-CHA159-15, on the other hand, covers the 4 to 6 GHz band. Like the RM-CHA90-15, it also offers 15 dBi typical gain and 1.3:1 typical VSWR. This model is ideal for users who need reliable horn antenna performance in lower microwave frequency ranges while maintaining similar gain characteristics and measurement consistency.

Although these two conical horn antennas operate in different frequency bands, they are designed around the same practical engineering priorities: broadband performance, stable gain, and dependable matching. This allows users to select the most suitable model based on their operating frequency without compromising on core electrical performance.
Both models can be widely used in EMI detection, orientation, reconnaissance, antenna gain measurement, and radiation pattern testing. In test environments, conical horn antennas are valued for their directional characteristics and predictable performance, which help improve measurement repeatability. For antenna engineers and RF system developers, these features are especially important when building or validating microwave systems.
For companies and laboratories seeking reliable conical horn antenna solutions, the RM-CHA90-15 and RM-CHA159-15 represent two practical options across key microwave bands. Whether your work focuses on 4–6 GHz or 8–12 GHz applications, these antennas provide a balanced combination of gain, matching performance, and application flexibility.
If you are looking for a professional horn antenna for RF testing, EMI measurement, or antenna characterization, these two models from RF MISO are worth serious consideration.
