[MT-AU Public] 802.11ac SXT's

Hi guys, has anybody used the new RBSXTG-5HPacD radios as yet and have any comments ? We have a couple of short P2P links we were looking at doing, about 1km - 3km, there is a bit of 5Ghz stuff already in the areas and was wondering how these handle a bit of interference, we only need 100M but was thinking about trying the new 802.11ac gear when Duxtel gets some in stock. Regards Paul
