Is this setup sufficient for a 4-5km LOS connection?
Bullet5 + 24dbi grid antenna
Yes...In fact, you may have to back off on your power output a little bit.

We installed our first Bullet5 on a Hyperlink 27dbiGrid shooting to a MT ap with 17dbi 90 degree sector/24dbm card. 25mile link.
MT ap reports 82dbm Rx, 78dbm Tx, 16db SNR, Tx/Rx CCQ 91/100.
We don't get those CCQ numbers with a NS5 at 4 miles!
"okey so from 24dbi to?"
Umm...no, I'd just leave it at the full 22 dBm output. I was thinking you might overload the receiver front end, but running the numbers shows you won't after all.
+22 +24 -112 +24 = 42 dB into the receiver which is near the potential 20 dB overload level.

since when MK reports statistics from a non MK device? :roll:
With Bullet MK reports only Tx for CCQ and Rx for Signal Strenght. :wink:

AirOS reports correctly on both sides of MikroTik. You can use the MirkOTik winbox side to see both sides of the link. This is a feature of the AirOS software.
Thanks,

I forget how it works beacause I've replaced the sector with mikrotik with NS2. It's smaller and the same results. My mistake :roll:
