Range test for SkyZone TS5823 5.8GHz 32CH A/V 200mW Mini FPV Transmitter. Maximum distance reached 988 meters, note it would have gone easily past 1km but my control telemetry was bleeping (damaged 2.4ghz aerial now fixed!).
Using Band E with Channel 4 at 5645Mhz with Boscam 5.8G 8CH AV Wireless Receiver RC805 and very cheap circular polarized antennas
Estimate maximum range in open area perhaps 1.5km (more with directional antennas)
Multiple places sell the transmitter, hobbyking sell a 'version 2' that is modified to reduce any issues with white lines across the image (note I have the version 1 and it is perfect) - link to SkyZone TS5823 5.8GHz 32CH A/V 200mW Mini FPV Transmitter (v2) on hobbyking (short url) http://goo.gl/0aU0SH
