Since the OP was almost a year ago, I hope that Boris got his setup finalized. I am getting more than 35m on my Immersion 5.8 gHz 600mw. I use a diversity array with the BlueBeam cloverleaf and a patch antenna mounted on a EagleEye antenna tracker. The majority of the time the BlueBeam has the best signal and the tracker hardly moves. I am flying out about 600 feet. I am currently using a Mondo Stinger 5.8gHz 500mw transmitter since I broke off the antenna mount on my Immersion and the new v2 is not generally available. Hope this helps you. If not let us know.
