Quadrifilaire 137 Mhz for satellite
I found that an excellent antenna for picking up these signals are quadrifilar Helix Antennas 137 MHz

2 Meter Array
Here is a little project that I can recommend to anyone looking for a small vertical phased array
2 meter 146MHz 5/8 Ground plane antenna
The reason for selecting the 5λ/8 wave ground plane is that for a simple single element antenna it appeared to have increased capture aperture when compared to the standard λ/4 wave length ground plane antenna and has a relatively low angles of radiation in comparison with other similar antennas
2 meter dipole antenna
The reason for selecting the 5/8 wave ground plane is that for a simple single element antenna it appeared to have increased capture aperture when compared to the standard 1/4
2 Meter RDF dipoles
Is a functional prototype of a upcoming Byonics product in our T-Hunting / RDF product line

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
