The wireless speed's are what they are.<BR>
<BR>
Ie the minimum speed is 1mbs using a wifi protocol.<BR>
<BR>
I would want to have a calculated min of -85 before an onsite test.<BR>

Ok Let's do a sample calculation now based on the actual equipment I own<BR>
<BR>
I'll use the calculator at<BR>
<BR>
<A HREF="http://www.afar.net/rf-link-budget-calculator/">http://www.afar.net/rf-link-budget-calculator/</A><BR>
<BR>
We'll assume that the setup at Binunyong has the maximum power output made up of 30db gain dish plus 8db power output and -2db cable loss = 36 dbm maximum legal power<BR>
<BR>
At my end on Mt Dandenong a 24 dbm ex galaxy dish plus 14 dbm power and allow 2dbm cable loss with a Ubiquity bullet with -95 db receiver sensitivity @ 1Mb/s<BR>
<BR>
That should give a receive signal strength of -84.3 dbm with a fade margin of 10.7db<BR>
<BR>
Not a huge margin to play with but arguable doable. The Ubiquity will probably do 256kbs at -100 or -105dbm so that should give a bit more elbow room.<BR>
<BR>

Hi Peter,<BR>
<BR>
<BR>
<BR>
<BR>
<BR>
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>
Kind Regards<BR>

By the way Peter<BR>
<BR>
<BR>
<BR>
What gain do those ex Galaxy slatted dishes have?<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>

Does anyone know the noise floor there too?<BR>
