Your antenna as others have stated should be fine. I would power up the
radio and check it before jumping to conclusions. If it was an RMA
return that was not the original radio they sent you there is a chance
they could have changed the diplexer in it to be the correct one. If
this was done they should have changed it in software too.

The antennas have to pass both the Tx and Rx channels, so no, they're
not high/low. They'll either be 10.0-11.7 or 10.7-11.7.
10835 is your low, so 11325 would be your high side, which doesn't
fall into that diplexer range either. WTF? Is your license for
10835/11325 H+V? This is IP20/820C, right? So each radio has two
diplexers. Is there only one label?

I had the Low radio on the Low end, so that was correct.
But are you saying for sure this radio cannot select that low of a
channel?
Also, now that I'm thinking of it, do the 3' Andrews dishes need to
be High/Low?
I was pretty sure the 3' dishes typically covered the entire 11GHz
band, right?
What do I do about the radios now?
I'm thinking of comparing the radio I got back from Ceragon with my
other radio and seeing if somehow Ceragon did something or put a
wrong part back on it.
Since it refuses to mount back on the antenna it used to mount to now...
Someone shoot me.

Yeah, that's not gonna work real well, or at all. Is this the link
where you had them backwards? Didn't you end up swapping them? Or did
you open them up and change the diplexers?

Ok, so maybe this is a problem and maybe not.
But our license says we transmit LOW at channel 10835MHz.
The sticker on the label of the LOW Ceragon ODU shows transmit at
10915-11207MHz.
Does that mean I have the wrong ODU for this license?
Or is the IP-20C radio that I have capable of that channel and it's
ok because that's just a sticker, not the limitations of the actual
ODU transmit.
Anyone know?
