Question: Can you send me price list?
Answer: Yes, please send your email inquiry to [email protected]
Question: Any chance to change to 2 or 5 Ghz band? 
Answer: Now our Transmitter frequency supports from 170~1500Mhz.
Question: COFDM-904T has HDMI input?
Answer: Yes, COFDM-904T has HDMI and CVBS input. It support Gopro camera.
Question: COFDM-904T is only 4 Channels?
Answer: COFDM-904T default has 4 frequency, if you need different or more, we will edit our software to do (170~900Mhz), Just send us your requirement details to [email protected]
Question: What about data rate? Support 8M-10Mbps?
Answer: Default is 3M, we also can support 8-10Mbps if adjust parameter.
Question: Can i set manually by me?
Answer: It is better to pre-set in factory and test passed before delivery. If need, we can also tell you the solution to change frequency.
Question: I need COFDM-904T work on 1080i 50 at least at 8-10Mbps
Answer: It is no problem.
Question: Can i set manually all the parameters by myself?
Answer: If you add PA (booster), then you can not; If you don’t need PA (booster), then you can (PA is hardware, if you change setting, hardware should be adjustable)
Question: Which is the max frequency value we can set?
Answer: 900Mhz, Need higher, please choose COFDM-902T
Question: If the band range is 300-900 i will tell you exactly 4 ones in between to set for me, then i will need constant data rate at 10 Mbps, modulation at 16QAM, FEC at 1/2 and Guard Interval at 1/32. Encoding at 4.2.2 if possible instead of 4.2.0, 200 Meters (NLOS) Non Line Of Sight and 500 Meters (LOS) Line Of Sight. RF power at 500 mW, remember, data rate MUST be fixed (not variable) at 10 Mbps, try this setting and let me know how it works (better if you can forward me a short video directly recorded from the HDMI output of the receiver – NOT SHOOTING A MONITOR SCREEN! At least we need 27dbm
Answer: OK, we can do above sample if you confirmed.
