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

A Parasitic Lindenblad Antenna for 70cm

Antenna for UHF VHF Links

Building UHF Antennas, W6PQL
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

Built and tested his the antennas, F5ETM
These are mainly airs for UHF and SHF, for some in circular polarization satellite traffic requires

Diplexer HF + 6m / 2m + 70cm
The DIPLEXER described here works for 0 to 52MHZ on one side and 2m + 70cm on the other side.

Dipolo-Bazooka
Questa antenna, realizzata con cavo coassiale di 52 Ohm, coincide perfettamente con l'impedenza presente al connettore d'antenna
