rocket dish polarity

[twinkletoes]

someone commented on the forum that the rocket dish was circular polarized, clockwise and counterclockwise.

this sounds great, in theory we get less interference from everything else, right?

but the datasheet clearly says "Polarization" "Dual Linear" (not "Dual Circular") and then gives Hpol and Vpol beamwidth.

what gives? where art thou fabled circular dual polarized dish?

was it just a figment of my imagination? and if so, why art thou forum contestants sayeth rocket dish is not usable in a CPE application with airmax sectors?

did you hook up the wrong chain to the wrong polarization on one side or the other?

The datasheet is correct, the rocket dish is dual linear polarized. So it should work just fine as an airmax CPE (or bridge, or PtP) with a Rocket M slapped on.

... Ah yes ... the only problem is that you need a left-handed monkey wrench to install it ;) ...

OK ... Mike Ford was apparently one of the people originally spreading the circular polarization story for a while. Scroll down to my post in this topic where I confronted him with the specs...

You will noticed that he acknowledged his mistake ... and he also deleted the post of his that I quoted :P

As far as I know, UBNT only sells products with H or V polarization.

Yes that was my bad. But we only sell H and V pol devices.

Thanks,

So, with a rocket M5 does it matter which polarity goes to which port on the radio? I have a mix of your sectors and rocket dishes, but I also have to use some other antennas since I can't get stock on the rocket dishes.

Just curious if the MIMO code sorts this out for itself or if I must make sure all the different types of antennas have the same polarity on the same port.

You should have all the radios connected
to the antennas in the same way as
each other.

In other words, chain0 should have the
same polarity on both ends. Dave
