AX86U-Pro, transmission power on 2.4 and 5Ghz, and antenna gain?

[snovvman]

For the AX86U-Pro, does anyone know the maximum transmission power for 2.4 and 5Ghz in the US? I know it's FCC regulated but also know that manufactures may not go up to the limit.

Also, what are the antenna gains for the three externals and one internal?

Thanks.

Find the FCC ID on the router and check the test reports on the fccid.io website. All the information will be there.

A little contribution. Even though the FCC ID Database for the RT-AX86U Pro states that the Power Output is roughly 990mW (about 30dBm), that's not what my US unit reports:

2.4GHz band (3 antennas), channel 5 (@ 20MHz):
 wl -i eth6 txpwr_target_max
 Maximum Tx Power Target (chanspec:0x1005):      23.50  23.50  23.50

5GHz band (4 antennas), channel 161 (@ 80MHz):
 wl -i eth7 txpwr_target_max
 Maximum Tx Power Target (chanspec:0xe39b):      24.00  24.00  24.00  24.00

The above numbers do not include 1.50dBm of antenna gain. Adding that, we should probably expect to get 25.50dBm for the non-DFS 5GHz channels @ 80MHz, which translates to about 355mW. I'm not sure why the US units (at least, mine) seem to be so power-limited when compared to the Power Output stated by the FCC ID Database.

As a curiosity, after upgrading from Asuswrt-Merlin 3004.388.8_4 to 3006.102.4_0, I noticed wl -i eth6 txpwr_target_max (2.4GHz) was reduced from 25.25 to 23.50dBm, and it remained the same with 3006.102.5_0 (which I'm currently running). And since that is closed source from Asus, I presume the results for stock firmware should be similar or identical.

For comparisons, it would be great if a few fellow owners of US RT-AX86U Pro units could also post their results of wl -i eth6 txpwr_target_max and wl -i eth7 txpwr_target_max, along with the channel, bandwidth, and firmware version used. Thanks in advance.

24 dBm = 251 mW per antenna.
