Use Spectrum analyzer to get best (clear) frequency.

Hi.
Can you post your PTP configurations. and your antennas brand and model.
hi
yes my friend
antennas is dish ubnt 30 dbi
this is configurations in pic
i tray many configurations but its same ccq bad and net bad this configurations The distance its 9 km
Is there a video programming RB912 p2p ?
no 1 can hellp me ? is this RB912 have problem ?
DECREASE THE POWER!!!
-43 is too high!
30dB dish for 9 Km is excessive.
[My P2P with 28dBm dish, dual polarized, RB433AH + RB52Hn at 23,5Km do 180Mb/s effective with NV2 and 20MHz + 20MHz channel]
For link less than 10Km I use Sextant…
For link less than 5Km I use SXT…
The signal strength must float between -66 to -63 for optimal performance, or you obtain more ROS (return of signal) than 1:1
DO NOT USE WPA or TKIP as CRYPTOGRAPHIC PROFILE, but only WPA2 AES-CCM
Also, I see some error in wireless config, use my example for max throughput:
http://forum.mikrotik.com/t/2-sxt-ppp-one-way-signal-is-bad/74620/1
YOUR DISH ARE DUAL POLARIZED?
IF ARE DUAL POLARIZED HT must transmit and receive on both channel 0 and 1
IF ARE SINGLE POLARIZED HT must transmit and receive only on channel 0 and NOT on 1 [and also the module must be properly internal connected]
Remember to set: country=italy with your country!
Hi

I was unaware with this and that is why my CCQ float too much. Thanks for the information.
