Well, I must correct myself! While there is an integrated patch antenna, its
gain is part of the 25dBi total gain, not in addition to, so you are correct,
we are off by 9-10 dB and are too low. This explains the questions raised at
Wispapalooza and what you are seeing here. The good news is that this is
fixable via SW and we will obviously get this fixed ASAP. I'll let you know
when we have an Open Beta load for you to use, it should be within a day or so
here, and we will expedite a formal released load fixing this.
Regards,
-Aaron

Darren -
We'll take a look but the external gain for 450D is locked because that is the
property of the HW with the attached dish and radome. This is not changeable
intentionally.
The internal HW of the 450d is actually an integrated 450SM in a new housing,
so there actually is some internal gain via the 9dBi patch antenna, so that
would account for the difference. So TxPower + internal patch gain + external
dish gain <= EIRP would mean -4 is our max TxPower for 5.4 FCC to stay <= 30 dB
EIRP.
However, we will take a look - there was some feedback at Wispapalooza that
some customers were having issues installing these in 5.4G band, but the tx
power should be correct.
Regards,
-Aaron

Aaron,
I had a question about a change Cambium implemented on the 450D radios,
although it's not new to 14.1.1 (I think it started in 13.4): the Power
Control section on the Configuration -> Radio, External Gain setting is no
longer adjustable, and is locked in at 25dB. OK, but the radio seems to be
thinking it's got some sort of additional gain, because it won't transmit
higher than -5dB (reported in Link Status). Shouldn't the EIRP in the DFS band
be 30dB, so it could transmit as high as 5 dB? This seems to be causing a major
connectivity issue in the 5.4 band, but not in the 5.7 band, where transmit
power is reported as anywhere from 16 to 22dB on the same SM to the same test
AP.
Why the disparity? Is there any hope for using 5.4 GHz frequencies on a 450D SM
to a tower you could not hit with a football?
