Hex-Beam Video
- A rotating HexBeam antenna video from F5NZY in Paris France
An automatically tuned 7-30MHz mobile antenna
- This is a base-loaded vertical antenna that mounts on the car's roof. The loading coil is designed as a variable inductor, with a three-legged chariot that travels up and down inside the coil, with grooved brass wheels running on the coil turns, and driven by a slotted rotor tube.
Experiments with a Moxon Rectangle antenna
- An easy to build moxon antenna for portable use.
A Moxon Rectangle is a two element beam, where both elements are folded towards eachother.
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.
Vertical plane antennas' beaming comparision
- Animated quad and yagi comparison. You can see antennas' characteristics behavior in a vertical plane with changing of the height.
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
Antennas basics
pop
- An antenna study guide by NZART, cover basic topics like dipoles, wave lenght calculation, baluns, beams, dummy loads, and measurements.
Mini-Beam Geometry Basics
- There is a natural progression of the geometry of
the "mini-beams" deriving from the basic yagi, which in itself owes a lot to the common dipole. By Dick Stevens, N1RCT
Why a Beam Antenna

30m QRSS Receiver
- Article on a QRSS receiver for 30 meters band
VectorFox
- 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.
Amateur Radio RF Safety Calculator
- University of Texas Amateur Radio Club RF-Calculator. This is a main beam power density estimation program intended for use as part of a routine evaluation of RF safety compliance with FCC regulations
