I’m using a Really Right Stuff tripod for the Atomos Ninja Blade monitor and ProRes recorder (overkill, but it’s the tripod I usually have with me), and have clamped Lightbridge to the tripod center stalk using a music stand mount for a tablet. This mount is versatile because the ball system also matches the ball system used by the Phantom 2 Vision+’s phone mount, so you could also use that system to mount a tablet to your radio (and run a thin HDMI cable to Lightbridge). Lightbridge is on the heavy side for this particular tablet mount, but it seems to be working, so far.
Regarding HDMI cables, you want something fast, thin, and long. I’m using a 16’ PNY Smart Active HDMI cable, which works well.
