Cross Yagi antenna with circular polarization for satellites
To design a set of LHCP circular polarization VHF and UHF antennas to work in low-orbit satellites
post 29 Jan 2024
Antenna for UHF VHF Links →
Loop per i 144 mhz
L'antenna si compone di un normale connettore da pannello, saldato al cerchietto di rame argentato ai cui estremi andra' saldato un compensatore Philips
Magnetic Loop for the 2m band
This loop copper is made of 50cm of 4mm soft tubing. The capacitor of two 1mm circular plates with about 3cm diameter torch-brazed to the loop conductor

Questo tipo d'antenna e' mutuato direttamante da una Yagi col vantaggio del minore ingombro e della maggiore robustezza meccanica
