Looking at the MikroTik RB911G-2HPnD-12S mANTBox radio for a permanent AREDN node installation. I don't see this device on the hardware matrix, but I do see there is another MikroTik RB911 device listed under 5Ghz hardware.
Anyone have any experience or knowledge if the AREDN firmware can be loaded onto this device?
Thanks!

MikroTik RB911G-2HPnD-12S mANTBox - No Channels -1 or -2 ??

The main advantage to these devices (both in 5GHz and 2.4GHz) is that they are like a 30dBm BaseBox device that have a built-in 120 sector panel antenna, which would save you at least $100 per device if you don't have to buy a separate sector antenna.
I'm all for this, especially seeings how our source of cheap sector antennas dried up (Altelix no longer sells WiFi MIMO antennas).

We're working on testing that here. I'm sitting right next to LUN in a meeting and the one he received currently appears to only be giving options for channels 1 thru 14. Those also are identified by center frequency instead of channel number. Also, for installation, that one was unreachable until we allowed it to obtain an address via DHCP. I've got the bare board sitting at home I will be trying as soon as the antennas I ordered arrive. The raw board takes MMCX connectors, instead of the u.FL or RPSMA connectors that are more common.
Does anyone have any ideas on getting it down to -1 or -2? everything I can see looks like it's the same chip as on the 912-2HPnD in the basebox.
Yep - tried loading the mANTBox with "aredn-3.19.3.0-mikrotik-nand-large-sysupgrade.bin" and then with the nightly build "aredn-1190-1272c57-mikrotik-nand-large-sysupgrade.bin", both appeared to be working fine except for the ability to select -1 or -2. I have attached the support data file for people smarter than me to look at.

Let me know if that makes everything work, to get into the nightly build.

Does this mean we will soon be able to flash the mANTBox 19s ... aka ... RB921GS-5HPacD-19S-US with the nightly build?
Many thanks,

Sorry, guess I should have realized that ... but thank you for the clarification. :)

So at the risk of sounding stupid, I did a little stumbling around and realized I don't have the slightest idea where to find the file you mentioned. I surmised from looking at other posts that I modify this file on the live node, but I haven't a clue how to actually do that. Any help would be greatly appreciated.
Thank You!
from command line, "vi /www/cgi-bin/perlfunc.pm" and do the edit.

I'll do more testing of the MikroTik RB911G-2HPnD-12S mANTBox this week and post the results. Hopefully this (and 2 more) will be a good candidate for a permanent node installation.
Thanks for the help!!

Late in 2020 I installed NB firmware on three new Mikrotik mAntBox units (2HPnD) and got the “Untested Hardware” message after successfully booting the elf. Logged into the units and added a section to perlfunc.pm with Mikrotik RouterBOARD RB911G-2HPnD (added “RB” prefix to 911G), and the untested msg disappeared. Installed the sysupgrade.bin file, and after final config steps they are running fine. This board string needs to be added to the firmware image to eliminate the "Untested Hardware" message.
I have been impressed with the Mikrotik mAntBox RB911G-2HPnD-12s so far. The build quality seems more solid than many other units. For example, the access door is quite substantial and is secured with a thumb screw. I like the fact that the RB911G board is integrated with a well-shielded 12 dBi 120 deg sector antenna in a single enclosure that serves as the radome. It has two power input options (PoE or 5.5mm DC jack), and it takes the nand-large image which displays lots of free memory after flashing with AREDN firmware. It also has 1W (30 dBm) RF output, dual-chain radio, and 10/100/1000 Ethernet port. They only cost about $85, which seems like an attractive price point for everything you receive.

A friend asked me to do an initial AREDN firmware flash on the mANTBox 15s (RB921GS-5HPacD-15S) unit, but this model doesn't appear to be listed on the supported platform matrix. I am thinking about trying the stable release 3.22.1.0-ar71xx-microtik-vmlinux-initramfs.elf but thought I'd ask here first.
Does anyone have any advice on whether or not this might work? Should a try a different build? If it doesn't work will I be running a risk of damaging it?
RB921GS-5HPacD-15S is not supported.
Note the 'ac' in the model name.
I hope this helps,
