PowAbeam Antennas offer a range of high-performance VHF and UHF Yagi antennas conceived by Derek Hilleard (G4CQM) and hand-built to order by The DX Shop in the UK.
Advanced Optimized Wideband Antenna (AOWA) style and low-Q Yagis, designed for wider bandwidth and improved stability during rain, snow, or wet weather conditions.
Derek is one of the very few Radio Amateurs to own the powerful design software from Brian Beezley (K6STI) both YO7 and AO 'professional' versions.
