WR112 Coaxial Input Standard Gain Horn

WR112 Coaxial Input Standard Gain Horn Antenna for Lab and Field Testing

This product is a solid example of a Standard Gain Horn Antenna, built with a coaxial input design. The model uses a WR112 (BJ84) waveguide size but features an N K type coaxial connector for easy hookup. It is made from aluminum with a conductive oxidation finish and painted in sea grey. This finish adds a layer of protection while keeping the antenna lightweight. As a Coaxial Input Horn, it is made for quick and simple connection to standard RF gear. Users do not need special waveguide adapters or complex tools. A regular coaxial cable is enough to get it working. This design choice makes the antenna a good fit for labs and field work where speed and flexibility matter. Its straightforward build also keeps the cost reasonable, giving users good value for their money.

This horn antenna operates across a frequency range from 6.57GHz to 9.99GHz. The Voltage Standing Wave Ratio (VSWR) is rated at 1.5, which shows solid impedance matching across the band. The antenna provides a stable 10dB gain, offering reliable directional radiation for most testing tasks. The coaxial input uses a standard N K type connector, which is widely available and easy to work with. Other connector types like SMA can also be offered depending on the frequency band and power needs. The coaxial feed allows the antenna to connect directly to signal sources or test equipment without extra waveguide sections. This saves setup time and reduces the number of parts needed on the test bench. For many engineers, this simplicity is a big plus in daily work.

One clear strength of this Coaxial Input Horn is how well it fits into lab environments. Unlike waveguide input models that need precise flange alignment and clamping, this antenna hooks up in seconds. Just screw on the coaxial cable and it is ready. This makes it great for quick tests, educational demonstrations, and situations where the antenna gets moved around often. The antenna is widely used for signal transmission and reception in the microwave band. Its main application areas include metrology, testing, and communication. For people working on system calibration, component evaluation, or antenna pattern measurements, this unit provides a stable and repeatable reference. The performance stays consistent across its operating range, giving users confidence in their test data.

In practical use, this Standard Gain Horn Antenna handles a variety of professional tasks well. For testing labs, it serves as a standard source antenna for gain measurements and system validation. Its 10dB gain and low VSWR help produce clean and trustworthy results. In the communication field, it supports microwave signal transmission and reception for equipment checks and link testing. The aluminum build keeps the antenna light, which is helpful when mounting it on stands or positioners. The sea grey paint gives it a professional look while protecting the metal underneath. Whether used in a university lab, a commercial test house, or an R&D facility, this antenna gets the job done without fuss. It stands as a good example of how a well made Coaxial Input Horn can meet the needs of modern microwave testing while keeping things simple and cost effective.
