23cm-1296MHz Field Day Yagi
When I started building up 23cm / 1296 MHz transverter hardware, I knew that I was going to have to similtaneously make at least one antenna to suit
23cms Quadrature hybrids
The critical dimensions are the case and line, I have had 30 lines cut with a laser cutter to better than 0.1mm tolerances and I am having some boxes milled from brass. All will be silver plated
3 bands Antenne voor 3,13,23 cm banden
For the 3 Cm Band a copper tube is used that normally serves for water supply
70 cm 3cm Beacon Antennas
A set of waveguide double-slot antennas for 13 cm to 3 cm beacons and an Alford slot antenna slotted cylinder antenna
Doppia bi quad 23cm
Ha un guadagno tipico di circa 10 db, ed un impedenza caratteristica di 50 ohm
