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.

Cobham Antenna Systems, a market-leading supplier of antennas, is proud to announce the sponsorship of the Liverpool University Unmanned Aircraft Systems (UAS) team taking part in IMechE's UAS Challenge 2015.
Cobham has supplied antennas, cables, connectors and has provided its expertise to the Liverpool Team. First test reports, from the team, showed exceptional results with operational range more than doubled when compared with the standard 'off the shelf' antennas.
This improvement in range was prior to installation of a ground plane for the antenna being mounted on the UAS which is expected to further enhance the useable range. The results clearly demonstrate the importance of the antennas in UAS communications range, which is critical for their safe operation and use.
Nickolay Jelev, part of the Liverpool team, had this to say:
"Thank you to the team of engineers at Cobham Antenna Systems, Newmarket who helped us secure the communications antennas for our video and telemetry links. These will provide us with communication links beyond 1km, while adhering to all UK/EU transmission power and frequency regulations."
