Antenna 433MHz 2dBi Weatherproof Directional IP67

433MHz 2dBi Weatherproof Directional IP67. Cable to SMA. Thru-Hole Mount. VHF /UHF

  • Directional antenna concentrates the radiation in one direction, to maximize signal strength.
  • The limited beamwidth reduces "signal noise" / interference from other WiFi networks and third-party wireless devices, resulting in much greater performance of the device connected to this antenna (especially as compared to omni-directional antennas, which pickup 360-degrees of signal noise.

Compatibility with wireless standards & applications :

This directional antenna's range of frequency band compatibility in the 412-440 MHz frequency band range, its very low broadband VSWR at 2.0 , and impedance matching to 50 Ohm gear, makes it suitable and compliant for all the above applications.

Mounting:

  • Mount on any panel or board that you can drill a hole through, such as a ceiling panel, wall or drywall.
  • Easily mounts in a ceiling tile, by drilling a hold in the tile of the same diameter. Antenna has a nut and washer to mount the antenna on a ceiling mount.
  • Mount on ceiling or wall panel so that the antenna faces down from the ceiling, or horizontally from the wall.
  • Can be mounted securely inside or outside, with its 22mm long screw thread
  • Dimensions:
    • Largest diameter: 78mm
    • Smallest diameter of antenna body: 63mm
    • Depth (or height): 23mm.
    • Diameter of through-hole mount: 11/16 inch (17mm) including outer part of threads.

Waterproof: Totally sealed IP67 casing, with rubber seal gasket to prevent risk of water ingress.

Compact, puck shaped antenna for band 412-440 MHz: VHF / UHF frequency. Diameter of 80mm and height of 23mm, so this antenna will fit comfortably on to most surfaces. Commonly used for a host of applications in demanding environments: Vandal prone areas, outdoors and harsh weather condition locations.
