Travel router new version MT3000?

Working well for over a year now. I mouwtjes 1outside antenna on the boat and one as shown on the picture inside. All working fine. So instead of the standard antenna’s just 2 sma ports to Connect detachable antenna’s would be great.
I had to do it myself and lost the warranty but if this option becomes standard (like in example the old WRT54 from Linksys the user can choose what to use, omnidirectional or directional antenna’s.
