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. Its antenna gain is between 5dBi and 6dBi, the forward/reverse attenuation is up to 20dB.
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.
Who invented the hex beam?
The original HEX-BEAM was developed by Mike Traffic, N1HXA, in the early nineties. Mike says his design was inspired by the snowflake. He spent much time in testing and analysis of the antenna and developed the nesting concept that uses an inverted umbrella frame to allow multi band operation.
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. The whole antenna weight is only 6-7kg (14 lbs), making it ideally suited for portable use.
What height should a cobweb antenna be?
20m, 17m, 15m, 12m, 10m operation. Compact and easy to handle – Around 8ft square. Doesn’t have to be too high – Reasonable performance at 10ft, with 20ft being the ideal.
Is a Moxon antenna directional?
The driven element and feedpoint is the front of the antenna, so tie the rope on the back and use the feedpoint to ‘aim’ the antenna in the direction you want to transmit.
How many antennae 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.
