Taha Beam – Six-Band Hexbeam by VU2TAH

Taha Beam is a six-band hexagonal beam for 20 to 6 metres, designed and built in Keralam by VU2TAH. Light enough for a TV rotator and small enough for a city rooftop, it gives the gain and front-to-back of a two-element Yagi — and it has been carried to DXpeditions and special event stations, including MARS's own 8T4I.

Why a hexbeam?

A hexbeam is a light, directional wire beam for several HF bands at once. Its wires are strung on an inverted-umbrella frame of six spreaders, so it gives real gain and front-to-back without a full-size Yagi, a heavy tower or an expensive rotator.

The design was developed in the early 1990s by Mike Traffie, N1HXA, who introduced the nested multiband "HEX-BEAM" commercially. Reviews in CQ and QST earned it a name as a pile-up buster, and before long home-brewers around the world were building their own.

The story behind Taha Beam

  1. 2014VU2TAH builds his first hexbeam from general hardware available locally.
  2. 2015A friend needs a hexbeam for his A7 (Qatar) operations, so a prototype is built from Chinese fishing-rod spreaders sourced in Keralam.
  3. 2016The prototype goes on air. Only 3 m above the roof of a two-storey building and running 400 W, it breaks pile-ups into the USA and works many rare DXCC entities.
  4. Version 1.0Encouraged by the results, VU2TAH builds hexbeams with high-quality materials for a group of hams — the first Taha Beams.
  5. Version 2.0The design is upgraded to export quality. More than 20 Taha Beams are now in use in over five DXCC entities, most of them in the Middle East.

Taha Beam features

  • Gain and front-to-back comparable to a full-size two-element Yagi
  • 50 Ω direct feed — no tuner, no loading or matching coils, low SWR
  • Low weight (about 10 kg) and low wind load for an economical mast
  • Small footprint (3.3 m turning radius), suited to urban rooftops
  • Turns with an ordinary TV rotator — no heavy-duty rotator needed
  • Broadband across each band for CW, digital and SSB
  • Built from high-quality hardware components
  • Portable enough for expeditions
