Grids and parabolic antennas with feed

[eco32 44]

In Australia, they have a strong tradition of using high-gain antennas, with versions available that are rarely seen. For starters, a factory 1300Mhz grid (I made one similar) and a 3.6HGz, in addition to the 2.4GHz 5.6GHz available in Europe.

900x600 Grids:

1.3  18dBi

 2.4 GHz 24dBi

3.5 GHz 27dBi

5.6 GHz

868MHz GHz Antenna

 

some feeds  were explained here : "Siple Dipole"  (which is no longer a simple dipole)

It would be good if the focal length(F/D) was also shown for each antenna grid...!!!

917 x 720 welded iron bars   (Pacific Grid) 917mmx720mm and 150mm deep  f/d = 0.38
900 x 600 split die-cast magnesium f/d = TBD
600 x 400 split die-cast magnesium f/d = TBD
400 x 300 split die-cast magnesium f/d = TBD

I happen to have all sizes, i will update

additionally something from Czech republic, not in production, but still available:
