MOXON Antenna Project - The MOXON antenna can provide radio amateurs with an excellent antenna system that is easy to homebrew and usually does not require any adjustment if made according to the dimensions specified by its designer. A typical MOXON rectangle can be built in a few hours, using X type of spreaders arrangement as discussed on this web site.

Cebik Moxon Rectangles - The Moxon Rectangle is growing in popularity as a compact 2-element array that approaches a full-size 2-element in gain but with a far superior front-to-back ratio and a direct match for the standard 50-Ohm coaxial cable.

GMRS J-Pole Antenna - Build a j-pole antenna for the GMRS/FRS radios. These radios are the type you can buy at sporting goods stores such as REI, Cabelas, etc. There are several radio manufactureres who make GMRS/FRS radios with removable antennas. This antenna can increase the range of these radios by miles!

2m Band VHF antenna pre-amplifier - Homebrew pre-amp for 144-146 MHz amateur band and OSCAR Satellites, using BF981 Dual-gate MosFet. Gain ~15 dB, NF=1dB.

Garex VHF preamp - It is available for spot frequencies in the range 40 - 250MHz, where a typical gain of 26dB can be achieved

144 MHz preamplifier with BF981 - Design of a preamplifier for 144 MHz with 1 dB NF and 23 dB gain using BF981. This amplifier is using a low cost silicon MOSFET (BF981 from Philips) to give more than 20 dB gain with around 1 dB noise figure on 2 meter.

Antenna Noise and Signal Cancelling at LF - By using the signals from two antennas, controlling their relative amplitudes and controlling the phase of one of them, unwanted signal or unwanted noise can be phased out. Circuitry is described which uses the signal from a wire antenna to provide selective cancelling against the signal output from an LF loop antenna.
