Introduction
Standard gain horn antennaOLB-42-20WR-42is also known as a waveguidehorn.
This WR-42standard gain horn antenna has a20dB nominal gain and a square cover flange.Our20dB WR-42horn antenna has a minimum frequency of 18.0GHz and a maximum frequency of26.5GHz.
Standard gain horn waveguide antennaOLB-42-20has a vertical beam width of18.85and horizontal of20.45degrees at 3 dB
The IEEE K band is a portion of the radio spectrum in the microwave range of frequencies from 18 to 27 gigahertz (GHz). The range of frequencies in the center of the K band between 18 and 26.5 GHz is absorbed by water vapor in the atmosphere due to its resonance peak at 22.24 GHz, 1.35 cm. Therefore these frequencies experience high atmospheric attenuation and cannot be used for long distance applications.

FAQ
1. How do I know that you have sent the products out?
Once the products are sent out,a tracking number will be provided so that you can check where your goods at all times
2.How you will send the goods to us?
We will send the goods to you by DHL, FEDEX, UPS, EMS, AIR etc.
3.what is the interface of the antenna
There are two kinds of interfaces of SGH antennas : standard wave guide interface.Coaxial interface .
4.What kind of interface do I need ?
We recommend coaxial interface if the SGH frequency below 50GHz. If the frequency up to 60GHz , we highly recommend use waveguide interface.
5.What kind of coaxial interface do you have?
There are kinds of coaxial interfaces ,they are divided by the difference of the frequency.
DC – 18GHz usually we use SMA or Nconnector.
DC-26.5GHz usually we use SMA or 3.5mmconnector.
DC-40GHz usually we use 2.92mm or 2.4mmconnector.
DC-50GHz usually we use 2.4mm or 1.85mmconnector.
DC-67GHz usually we use 1.85mm or 1mmconnector.
UP to 67GHz usually we use 1mm connector.
