I'm a noob to FPV and have recently put together my first kit of hardware. The setup operates well enough in most ways, but the useful range is only about 50m. This is not what I would expect with a 600mW transmitter.
Here's my setup:
500mm quad with CF frame
Boscam TS5828 video TX
Runcam 2 live video out as source
Bulkhead-mounted quadrifiliar antenna
4" RG316 cable to connect TX and antenna
Diversity monitor and FatShark Dominator goggles
I get the same performance with the cheap monitor and the goggles, so I'm inclined to think that the issue is on the transmitting end. My only lead is the antenna cable. RG316 is only good to 3GHz, but a 4" run should not cause nearly that much attenuation.
The transmitter gets about as warm as I would expect for such a device. It's clearly doing SOMETHING. I have already sorted out an issue with the telemetry radio and video TX bulkhead connectors shorting through the CF frame. Both radios were replaced after that, and are now electrically isolated.
Any input would help. Thanks for your time.
