I wonder how to set the frequency above 5825 in superchannel? I have two SXT HG and at frequencies above 5820 do not want to connect. The same thing with new two SXT AC. Freq. mode: superchannel, country: no_country_select and all channels above 5820 can't connect. Strange thing: SXT AC, superchannel mode, frq. 5820, and channel width 80Mhz/Ceee work fine, so additional channels operate above 5820?

So for what is mode superchannel? In this mode max frq. is until 6100, but usable only 5825, such as for example for India? But for Netbox spec. is: frequency range 4920-6100 MHz. SXT AC has different radio chip, or is it ROS problem ??? Why frq. above 5825 don't work???

Mode superchannel 5825 and Ceee work fine. Additional channels operate above 5825, so I think is rather ROS limitation.

I found a trivial solution to this problem . Default scan list is to short. Station scans only channels from scan list to connect. Just add in station config channels 5825-6100 to the scan list and...voilà !!!! all sail, play and booming

Just for test purpose:
/interface wireless
set [ find default-name=wlan1 ] ampdu-priorities=0,1,2,3,4,5,6,7 band=\
5ghz-onlyac basic-rates-a/g="" channel-width=20/40/80mhz-Ceee disabled=no \
frequency=6040 frequency-mode=superchannel l2mtu=1600 mode=bridge \
nv2-cell-radius=10 rate-set=configured ssid=vbridge supported-rates-a/g=\
"" tdma-period-size=auto tx-power=0 tx-power-mode=all-rates-fixed \
wireless-protocol=nv2

Bandwidth Test directly on SXT AC: stable UDP traffic about 400MBit.
Master channel frq. 6040!!!! Channel width 80mhz Ceee. So additional channels very high, some above 6100!!! Is this outside of physics? Or very good equipment, software and chipset but weak antenna at the extreme channels - significant power drop.

Thus killing the competition! I know it's licensed band in my country, but this stuff really works for a ridiculous price. Not important that equipment is operating outside the laws of physics The fee for a license is not so high, pure bandwidth, equipment for pennies, my congratulations!

Now I'm waiting for NetBox5. With a good antenna it will be driving like hell!!!

I made a mistake previously, so I removed my post. The SXT ac chip actually supports 4920-6100 minus the bandwidth.

what about SXT-5HPnD ? are they also support 4920-6100 ? and what are their antennas frequency range ?

Thanks

Yes, it would be more reasonable to check the antenna supported range, since the wireless chip supports a very wide range

here it is

this mean 5400-5500 is best for the horizontal 5200-5600 is best for vertical ? thanks for this information....
