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 Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Cobham Antenna Systems, a market-leading supplier of antennas, has developed a range of dual-polar MIMO sector antennas covering the UHF, 2GHz, 3 GHz, 4 GHz and 5 GHz bands. The range offers excellent coverage (azimuth beamwidths 60°, 90° and 120°) with peak gains of 14 - 17 dBi.
All antennas in the product range include interleaved vertical and horizontal (V&H) polarised antenna elements within a single aperture. This results in very compact, lightweight units with rugged and UV stable radomes.
Performance across the range is excellent and extremely consistent, as are the radiation patterns for a single antenna and also across polarisations. This makes the range an ideal choice for system roll-outs, even if frequencies are likely to change during planning processes.
The range also offers multiple benefits to installers and operators including: Reduced tower wind-loading (compared with two separate antennas); Lower cost for installation; Lower cost for tower rental; Lower cost for transport.
The most important thing we build is trust. We protect lives and livelihoods with our differentiated technology and know-how, operating with a deep insight into customer needs and agility. Our innovative range of technologies and services solve challenging problems in harsh environments across commercial, defence and security markets, from deep space to the depths of the ocean, specialising in meeting the growing demand for data, connectivity and bandwidth.
We employ more than 12,000 people on five continents, and have customers and partners in over 100 countries, with market leading positions in: wireless, audio, video and data communications, including satellite communications; defence electronics; air-to-air refuelling; aviation services; life support and mission equipment.
