Email Microwave Antennas ANTENNA TYPESDirectional/Flat Panel Antennas - FPA and LPA• Low profile• Gain up to 32dBi• Frequency range from 250MHz to 18GHz• Multi-layered technology for bandwidths up to 15%• Polarisation can be circular, linear or dual slant• More efficient than wishesA directional antenna radiates in one direction giving increased gain. The gain of the antenna is determined by the number of elements. The more elements the higher the gain and the smaller the HPBW.Flat panel antennas can be highly directional with narrow azimuth and elevation radiation patterns for pinpoint accuracy in a communication network.All antennas are tested to ensure that they meet their quoted specification, with supporting technical information and radiation pattern data available.If the application requires a robust, discreet antenna mounted flat against a wall, or on a mast where a smaller antenna would be beneficial, this type of flat panel antenna provides the best option. They may be painted to blend in with the surroundings. An antenna is installed in a prominent position in St Pancras International Station but unless you know exactly where it is, you will not see it.Low wind loading and robust construction enable our antennas to be mounted in the most demanding of environments such as the Channel Tunnel Rail Link where trains travel through tunnels at speeds of up to 150mph.
