Antenna offers between 10 and 15 dB of gain using a low-noise preamplifier mounted at the antenna with power fed through the coax from a USB power source.

Last week Winegard launched the FlatWave Amped Antenna —a new version of its FlatWave antenna with a built-in preamplifier. Flat antennas with amplifiers aren't new—the popular Mohu Leaf introduced an amplified version, the Mohu Leaf Plus, some time ago

Companies have been looking for ways to improve antennas: increased efficiency, increased bandwidth and ways make them smaller

Smart Antenna Technologies has announced it has a single antenna technology for mobile devices, allowing multiband coverage with performance matching that of separate antennas

The ability of receivers to reject signals outside the frequencies they are trying to receive is becoming more important

The new product line is designed to offer a cost-effective means of transitioning low-power analog broadcasters to digital service.

If a practical filter can be built using the technology at low cost, it will have application in almost every area of RF communications.

Researchers at the University of Bristol's Communication Systems and Networks Group have developed a new Wi-Fi test process that combines 3D antenna measurements with in-home virtual reality modeling
