Question: Can you send me the price list?
Answer: Yes, please send your email inquiry to us.
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,&nbsp;COFDM-904T has HDMI&nbsp;and CVBS input. It supports 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 us.
Question: What about the 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 the 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&rsquo;t need PA (booster), then you can (PA is hardware, if you change the setting, hardware should be adjustable)
Question: Which is the max frequency value we can set?
Answer: 900Mhz, Need higher, please choose&nbsp;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&nbsp;will need constant data rate at 10 Mbps, modulation at 16QAM, FEC at 1/2 and Guard Interval at&nbsp;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&nbsp;MUST be fixed (not variable) at 10 Mbps, try this setting and let me know how it works (better&nbsp;if you can forward me a short video directly recorded from the HDMI output of the receiver &ndash; NOT&nbsp;SHOOTING A MONITOR SCREEN! At least we need 27dbm
Answer: OK, we can do the above sample if you confirmed.
Question: Do you have any device, I can get a video at my computer?
