RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

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/profile is critical.
The FPA-0.7-2.7R/2319 covers the frequency range 700 MHz to 2.7 GHz and has a beamwidth of 60° x 60°. It 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.
Cobham Intros First in a Range of High Power Spiral Antennas
The narrow beamwidth helps to ensure that the disruptive signals are targeted where they need to be while reducing the
effect on friendly areas.
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.
