Greetings All, I had to drop a camera down a 6 inch diameter steel well casing to see what was going on. I used one of the tiny ubiquitous color cameras with a built in transmitter. I don't know the what the transmitting frequency is but the antenna wire is about 2 inches long. The camera was lowered down the well casing without touching the sides ar anything else. While watching the image on a little monitor the image would degrade in certain spots. The degradation was repeatable and only happened in certain spots. Is this because the signal bounces inside the casing and interferes with itself? Thanks, Eric
