To design a set of LHCP circular polarization VHF and UHF antennas to work in low-orbit satellites

Coaxial dipole VHF UHF
Here is a homebrew coaxial dipole built from a small stainless whip

Dipolo bibanda VHF/UHF da finestra
Dipolo verticale bibanda 144/430 MHz un semplice, economico ed efficiente dipolo verticale da finestra

Four element 2 meter quad antenna
Each element is built on a separate hub so theantenna can be taken apart. The boom is made from common schedule 40 PVC

Half wave dipole
The simplest antenna not only for VHF, CB and the like is bipolar the so-called Dipole, can be easily assembled at almost zero costs, but has some disadvantages, such as low gain and low directionality
