The FPA-0.7-2.7R/2319 offers high power, high gain and circular polarisation within a compact, low profile, rugged housing. It is suitable for multi-band communications as well as cellular countermeasure 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 or profile is critical.
The FPA-0.7-2.7R/2319 covers the 700 MHz to 2.7 GHz frequency range and has a beamwidth of 60° x 60°. It has a peak gain of 10dBiC and has been designed to handle up to 150W. However, Cobham claims that the antenna has the potential to operate efficiently at a much higher power.
The company adds that 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 beamwidth helps to ensure that the disruptive signals are targeted where they need to be while reducing the effect on friendly areas. Cobham claims that providing circular polarisation ensures that the antenna will couple with any polarised linear signal, giving more chance of disrupting hostile systems.
The high power spiral range currently includes four products covering 0.4 – 6.0, 0.7 – 2.7, 1.7 – 6.0 and 2.0 – 5.9 GHz.
