A Lowband Antenna that is Almost Free
- The Shunt-fed Tower, an effective Low Band Antenna, uses your beam as a capacitive top-hat and only needs a simple feed network and a good ground system to work DX on 80M and 160M.
The 5 Bands Wire-Beam
- This wire-beam has one radiator-element, feeded with 450-Ohm-Wireman-twinlead and needs an antenna-tuner. For the bands 6m, 10m, 12m, 15m, 17m and 20m bended reflector-elements are used.
The support is a cross of 4 fibreglass-fishing-rods

Types of multiband antennas
- Types of multi-band antennas for the HF bands, from the horizontal end fed wire, to g5rv, log periodics, trap dipoles, vee beams and rhombic antennas.
Handi-Tenna portable satellite antenna
- Here is a high-performance hand-held beam antenna that is easy to build and guaranteed to improve your downlink from the LEO satellites over ANY rubber duck or mobile whip
Reflected M beam for 20 meters
- The Reflected M beam is made from a pair of wires formed in the letter M that are back to back. One M serves as a driven element and the other can be either a director or a reflector
KVK Antenna Systems
- The manufacturer of the NuBeam, Vipole, and the multi-band Quad-Folded-Dipole (or QFD for short) antenna. Also have a unique multiband vertical which can combine operation on multiple HF frequencies as well as provide high gain on 50, 144 and 438MHz in a single antenna.
- High Performance Lightweight Antennas. 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 dx-pedition and portable use.
- VectorFox is a software born to incorporate a PC into the fox hunting environment. VectorFox is able to take inputs from up to 5 sources, such as a 2m beam, a 2m signal meter, a TDOA, etc, and display the results on the screen. VectorFox also accepts Agrelo inputs. From these results the operator can choose which indication is best and have a line drawn on the map in the direction of the signal.
