There were no install instructions for the wireless card, nor does the laptop itself explain the antenna configurations. Based upon different carrier frequencies and the harmonics caused by modulation and distortion, a reactive load (having both inductive and capacitive qualities) will register different instantaneous reactive impedance depending on the applied signal. "Transceiver" is correct; however, if the device is only used as a receiver, then it is harmless. These are desktops, not laptops. The internal mPciE WiFi cards in modern laptops come with at least two coaxial connectors for antennas, often labeled as "Main" and "AUX".Or just numbered: "1" and "2" on other cards. Both.

The standing wave effectively resonates the properly tuned antenna much like a tuning fork resonates at its designed frequency of resonance, which causes electromagnetic waves to be radiated along the structure of the antenna. For the Best High Gain WiFi Antenna, you need better dBi level. It saves on wiring running through the screen surround, as there's never really much room through the hinges for it to go, and the M670 doesn't have much room for 4 antenna cables as well as inverter and LVDS display cabling. No antenna (or dummy load) and smoke appears... Generally, antennas (antennae, if you are not in the USA) have three elements: Director, Radiator and Reflector.
