Q: What's the bandwidth & noise figure of your receiver?

Here's a better screenshot of the bandwidth numbers, without the
text formatting that went on by my newsreader client:

Since my Rocket M2 radio is on channel 10, it looks like the
sensitivity is from -88dBm to -92dBm.

The 24dBi antenna has specifications he
http://www.balticnetworks.com/ubiqui...h-antenna.html
Which say:
€¢ Frequency Range: 2.3-2.7 GHz
€¢ Gain: 24 dBi
€¢ Hpol Beamwidth: 3.8 deg. (Rx Dish) / 6.6 deg. (Tx Dish)
€¢ Vpol Beamwidth: 3.8 deg. (Rx Dish) / 6.6 deg. (Tx Dish)
€¢ F/B Ratio: -50 dB (Rx Dish) / -65 dB (Tx Dish)
€¢ Max VSWR: 1.6:1
€¢ Polarization: Dual Linear
€¢ Cross-pol: Isolation 35 dB min

The Rocketdish RD-2G24 datasheet is he
http://www.balticnetworks.com/docs/rd_ds_web.pdf
which shows these specifications:

So, in summary, the 24dBi dish has a narrow bandwidth of 3.8° to 6.8°
degrees, and the receiver has a sensitivity of -90dBm ±2dB.

I don't know how to translate those facts into an interpretation of
the spectrum analysis noise charts provided in the OP though.
