Direction Finding Antennas
Direction Finding Antennas are antennas that are used to determine the angle from which the signal is received by the receiver. This antenna will exhibit greater sensitivity in a specific direction compared to other directions in space, enabling users to determine the direction of signals. This feature is very useful in defense and mission-critical applications, radar, aerospace, spectrum monitoring, test and measurement etc.
Selecting Direction Finding Antennas
When selecting a direction-finding antenna, it is important to know the parameters that you need to specify. Below is a list of the key parameters to look out for when selecting this antenna:
Antenna Design: These antennas come in various designs. They include array, dipole, parabolic, portable etc.
Frequency: This is the frequency range over which the antenna can operate.
Gain: It is the ratio of the power delivered in the desired direction to the power radiated equally in all the directions from an isotropic antenna.
Efficiency: It is the ratio of power radiated by the antenna to the power supplied to the antenna.
Type of Polarization: It is the orientation of the electric field radiated from the antenna with respect to the antenna axis. Different polarization types exist, such as linear, circular, RHCP, LHCP etc.
VSWR: It is the ratio of the amount of power reflected back to the input to the incident power. This parameter is represented as 2:1, 4:1, 5.6:1 etc. Generally, the more the VSWR, the higher the reflected power, and the lower the antenna performance.
Mounting Types: They are available in several mounting types such as mast-mount, vehicle mount, flange mount, tripod mount etc.
everything RF has listed multiple direction-finding antennas from the leading companies. You can compare products, view their specifications, and narrow down on products based on the frequency range, gain, polarization, mounting types, and other parameters. Once you find products that you need you can view product specs, download datasheets, request a quotation or more information on a product. Your inquiry will be sent to the manufacturer who will get back to you with the required information.
