I am designing a system and need a transmitter that will get an NTSC video signal (1 Vpp, 310 lines, 60 Hz) over 500m, line of sight, guaranteed no obstructions.
The only problem is that I can only supply the transmitter with 500 mW of average power. I was thinking something in the 100 mW range, and then I can use an antenna to boost the distance at either 900 MHz or 2.4 GHz, but I can't find any transmitters that meet the specification for under $225.
I would prefer a supply voltage of 5V DC, but up to 9V would work.
Thanks in advance.
