How does a hex beam antenna work?
How does a hex beam antenna work?
A hexagonal beam operates exactly the same way but instead of a driven element that is straight like a dipole, it is a wire bent into the shape of the letter M. The reflector, instead of being straight is also a wire bent into a large U shape.
How big is a hex beam antenna?
If you have a small area and want a monoband performance antenna then the Hexbeam will suit your needs. At only 6.5 meters across it will fit inside most gardens. The turning radius is only 3.25 meters. Compare this to a 20m yagi with a span of 10.75 meters and a turning radius of 5.75 meters.
Is a hex beam antenna directional?
A hexbeam, or hexagonal-beam, is a type of a directional antenna for shortwave, most often used in amateur radio.
How much gain does a hex beam have?
The hexagonal beam has gain of about 3 dB over a dipole when the target is broadside to the dipole as shown on the azimuthal radiation pattern chart to the right. The Blue trace is the dipole pattern and the red trace is the hex.
Who invented the hex beam?
The original HEXBEAM was developed by Mike Traffie, N1HXA, in the early nineties. It is true that an “M” over “W” configured yagi antenna that resembled a butterfly was earlier tried successfully.
Who invented the Hexbeam?
What is a spider beam antenna?
The spider beam is a full size lightweight tribander yagi for 20-15-10m, made from fiberglass and wire. It has been specially developed as a highly efficient antenna for portable use – a DXpeditioner’s dream.
How many antennas does a spider have?
Spiders typically have eight walking legs (insects have six). They do not have antennae; the pair of appendages in front of the legs are the pedipalps (or just palps). Spiders’ legs are made up of seven segments.
How does the g3txq hexbeam compare with other multi-band non-trapped antennas?
How does the G3TXQ Hexbeam compare with other 2 element multi-band non trapped antennas? There are not many popular multi-band antennas available that are not trapped or that include the WARC bands. The first two that came to mind were the 2 element StepIR, this is a pure yagi antenna with straight elements and no traps mounted on a single boom.
What is a hex beam antenna?
Build Your own Hex. The hexagonal beam (or known by many as the hex beam) has become a wildly popular antenna. It is a directional antenna that provides great performance and does not require a full scale, expensive tower. It allows the average amateur to compete with the big boys for DX and without spending your retirement to do so.
How is the g3txq hexbeam by mw0jze made?
The end of each spreader section is sleeved with aluminium ferrules to prevent them splitting when pressure is placed on them when they are bent to form the shape of the G3TXQ Hexbeam by MW0JZE. Two (2) cords are fitted to the ends of each spreader be means of an eyelet or similar non ferrous fixing.
How many bands does the hexbeam come in?
Normally due to size the Hexbeam comes in five (5) or six (6) bands from 6m to 20m. Each element is a separate entity and in no way reliant to any other bands. Adding or removing any element has little or no effect on the other bands. High Power Insulators.
