1:According to the blurb, the sextant has an RB711G as the base router,, can MT confirm whether this is a standard "unmodified" Routerboard, or has it been re-shaped to fit the enclosure.

2: Has anyone split the housing apart and sprayed the inside with EMC shield to improve its S/N performance.

3: I read somewhere in a forum comment by Nomis that new CPE/AP designs were on the way, something to compete with the ubnt Nano eg +20db gain. Is there any news on this?

The RB711-5HnD in the Sextant CPE is the standard RB711-5HnD. It was not modified or re-shaped. It fits into the casing without any modification.

thanks for the info, at least spares can be obtained without throwing the whole thing away.

Good news.

Has anyone tried removing the PCB and replacing it with the 711GA-5Hnd, making the sextant then usable as a ptmp (level4) license,,

The 711GA-5Hnd has power jack and usb port, does it still fit within the sextant case with these extras!

It should fit. With some effort, you can even fit a RB433 in there
