No, you have to convert rectangular to square and then square to circular to
do a rectangular to circular transition.
If the nose of the dish had a rectangular hole, then it would mate right up
without problems.

I guess I just don't know enough about the slight differences since I've
never seen a PTP800 ODU interface. But that's exactly what a Trango ODU
(just Remec OEM) does. The port on the ODU is rectangular and mates up
directly with the circular port on the dish. Is there a gap or something
for matching?

It would work to a certain extent but you will not have as much tx power
as you should and you will have RX loss.
Yes, everything else is the same. I would give it a try. It will
probably work in a pinch but best to fix it right for the long term.

Anybody know if an 11GHz PTP800 ODU will mate with a Trango dish? I know
the PTP800 ODUs are Remec rectangular, but the Trango dish is Remec
circular. But aren't the physical interface dimensions the same? The
Trango dish is just a round hole, so no plate to rotate to change
polarity.
Got a dead ODU on an ApexPlus-11 and I think I can get my hands on a
PTP800 ODU-B. I know Cambium/Ceragon has single and dual pol IP20/PTP820
Remec adapters now, so we're debating whether to fix the one end with
this or just swap to PTP820's.
