Error in Antenna Gain - decimal number expected!

Hi, I have hAP lite (RB941-2nD-TC) with 1.5dbi antenna gain.

When I tries to fix “Antenna Gain” field does not allow 1.5 dbi. Says “Error in Antenna Gain - decimal number expected!”.
1- Im doing something wrong? tries with . and , and nothing. I beleave Im not the only.
2- If I must choose between 1dbi or 2dbi. Which one have better performance with my hardware?

routerOS version 6.45.9

Thanks in advance!

There’s good news and bad news. On the upside, you don’t have to choose, there’s no dilemma. Downside is, it won’t take 1, only 2, i.e. MikroTik stole half dBi from you. :wink:
