A Dummy Load is a device used to simulate an electrical load during testing. In an RF System a dummy load is used to simulate an antenna.By using a dummy load instead of an actual antenna, the transceiver can be tested and configured without radiating radio waves.The Dummy Load is selected in a way so that it has a similar impedance to the real device that will be connected to the RF System.Not using a dummy load and leaving the port open, can result in some unwanted reflections which can damage the RF System.Also, using a real antenna in the testing phase can result in some unwanted transmission in the lab which will interfere with other devices and technologies being tested.Warning: When the input power is high than dummy provide, this is damage the dummy loadMaterial:Plastic + Metalcolour:blackPackage Contents:1 x Dummy LoadOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
