The paper deals with a problem of interference as a result of the mobile phone coupling into the cabling of a complexsystem. The phenomenon has been simplified to a problem of near field coupling between a radiating antenna and a wire placed near a metal plate in an open area. Numerical simulations based on Methods of Moments have been performed for various lengths of the wire. for di... https://www.roneverhart.com/Liftmaster-CSL24UL-Slide-Gate-Opener/
