Description

For 8.2 GHz, wavelength is ~36.6 mm. Horn aperture must reflect that; to keep decent gain + pattern, horn length + mouth diameter cannot be too small. Short ones will lose gain or have wider beam. Corrugations help with reducing sidelobes and improving cross‑polarization and impedance matching, but add some complexity / size. Connector type: SMA / N‑female are common; verify with vendor. VSWR: good ones maintain around 1.5:1 or better over 8.2‑12.4 GHz. Material: Aluminum is common, need good finishing if outdoors. Mounting & weight: lighter version (~0.8‑1 kg) is good; heavier ones will need stout support.
