If you’re talking about the grids with the gold anodized aluminum,
24db<BR><BR> <BR><BR>
The ex galaxy ones with a width of around 600mm, they are 24db
too.<BR><BR> <BR><BR> <BR><BR> <BR><BR>

Hi
tony<BR>
<BR>
The north and south 2.4 antennas
are facing wwn and wws. They are only 14db panels the range isn't suitable for
record attempts.<BR>
<BR>
BUT I did pickup gho north in the
past at the geelong side with the horizontal pol wave guide
!<BR>
<BR>
So it does work
well.<BR>
<BR>
Keep me informed of your schedule
as I'm happy to help out with the melbourne region
end.<BR>
<BR>
Cheers<BR>
<BR>
Peter<BR>
