A Parasitic Lindenblad Antenna for 70cm
A traditional Lindenblad antenna uses four, dipole, driven-elements to create a circularly-polarized, omni-directional radiation pattern. This pattern is ideal for accessing satellites

Antenna for UHF VHF Links →
His method of construction can be used on most UHF through "low" microwave Yagis, and is especially useful for the 33, 23 and 13 cm bands
Build a 2m 8db collinear for £20, M3FVB
I started to build the antenna by cutting four lengths of wire, the measurement is 38.75ins for a half wave 145mhz but I cut them at 39.75ins
These are mainly airs for UHF and SHF, for some in circular polarization satellite traffic requires
The DIPLEXER described here works for 0 to 52MHZ on one side and 2m + 70cm on the other side.
Questa antenna, realizzata con cavo coassiale di 52 Ohm, coincide perfettamente con l'impedenza presente al connettore d'antenna
