Greetings Folks, I have a video camera/transmitter unit that transmits in the 900 MHz to 1200 MHz range according to the spec sheet. It currently has a wire for the antenna that's 3.5 inches long. For optimum transmitting doesn't the antenna length need to be a length that divides evenly into wavelength? I will be enclosing the camera in a small plastic waterproof enclosure with batteries and a light. Then it will be lowered 70 feet down a 6 inch diameter iron pipe. It will be used to inspect the well casing and pump as well as to watch the water as it is being pumped. I want the best signal possible and was wondering how long to make the antenna if the present one doesn't work. Right now, in open air, a good signal is present at 100 feet. But I don't know how well it will work when lowered down the iron pipe. Thank You, Eric R Snow
