Cobham Antenna Systems recently announced the launch of the FPA-0.7-2.7R/2319, the first in a new range of high power, directional spiral antennas.
The FPA-0.7-2.7R/2319 offers high power, high gain and circular polarization within a compact, low profile, rugged housing. It is suitable for multi-band communications as well as cellular counter measure and security applications. The low profile housing means that this antenna can be used to replace much larger and more expensive, Log-Periodic, Horn or Conical spiral antennas and also be used in situations where height/profile is critical.
It operates from 700 MHz to 2.7 GHz and has a beam width of 60° x 60°. The antenna has a peak gain of 10 dBiC and has been designed to handle up to 150 W (with the potential of operating efficiently at much higher power).
The combination of high Power and high gain means that a very significant Effective Isotropic Radiated Power (EIRP) can be generated to increase signal strength to overload any hostile system at greater distance. The narrow beam width helps to ensure that the disruptive signals are targeted where they need to be while reducing the effect on friendly areas. Providing circular polarization ensures that the antenna will "couple" with any polarized linear signal, giving more chance of disrupting hostile systems.
The high power spiral range currently includes four products covering 0.4 - 6 GHz, 0.7 - 2.7 GHz, 1.7 - 6 GHz and 2 - 5.9 GHz.
