GAOTek provides affordable, safe and reliable transmission line testers, digital clamp meters and power meters for sale to the United States, Canada and globally. A transmission line is a specialized cable designed to conduct alternative currents of radio frequencies. Transmission lines are used for connecting radio transmitters and receivers with their antenna to distribute signals.

However, in power systems, transmission lines are a long conductor with a bundle that carries a huge amount of generated power at very high voltages from one station to another. The GAOTek Transmission Line Testers determine the voltage drop, transmission efficiency and line loss, which are affected by line parameters R, L and C of the transmission line. Leading technologies support our products for our customers to use.
