Wind instumentation on rotating mast

[Moonskater]

Hi, gals & pals
The rotating carbon wing mast is just about to be operational!
We´ve decided we want wind speed information from the top of the mast. and we are looking at Raymarine, Garmin or NKE as possible suppliers.
Who has experience, knowledge or other to guide us in the right direction regarding what supplier or system to use?
I´m excited about the wireless systems about, but, we are possibly going for a top trilight wich will need a powersupply anyhow, (regardless of the fact that it´s a rotating mast).
This is a continuation of our previous thread "Simply put, more speed" stating our aim to have this old production cat sailing at windspeed before she dies!
Constructive ideas appreciated!

Interesting challenge.
Other than mounting on the bow....This has an internal compass, so theoretical should be stabilized to mast rotation

This might be an option:

It has the direction sensors in the unit. Can feed data via NMEA.
