The novel coaxial monopole antenna design with an additional metal screen is presented. The radiation char- acteristics of this antenna are investigated depending on a dis- tance between the ground plane and additional metal screens. as well as on a size of the latter. Measured and calculated ra- diation patterns are compared within limits of the operative frequency band and their rev... https://www.roneverhart.com/Liftmaster-850lm-Gate-Receiver-Package-With-2-copyright-Remotes/
