Q

How could the ECO maximise the efficiency of the telemetry signal?

A

Use the tripod to propogate the signal Site the ECB with as few obstructions to BA wearers as possible Site the ECB with its back towards BA wearers Ensure ECB handles are not obstructed or held onto during use (the handle houses the aerial)
