  1. CellMapper is a crowd-sourced cellular tower and coverage mapping service.

  2. The RF Line-of-Sight tool allows users to easily drag-and-drop locations and obtain point-to-point line-of-sight information anywhere using Google Maps. This map is useful in planning and troubleshooting cellular networks for IIoT / SCADA monitoring applications.

  3. The ability to communicate over long distances generally requires a low radiation angle, meaning that an antenna must be placed high above the ground in terms of the wavelength of the radio wave being transmitted.

  4. Concept of Effective Height: If the input current at the antenna base were constant over the vertical height, the Effective Height would be equal to the physical height. The objective of our LF antenna design is to achieve maximum radiation in the vertical plane.

  5. These graphs vividly depict the bandwidth problem on the lower frequencies, with the results varying significantly with antenna height. Fig 1. EZNEC models of dipoles from the standard formula, fed directly with 50 ohm coax (blue line) or series matched (purple line).

  6. 14 Φεβ 2015 · To generate an RF coverage map using Radio Mobile Online, all you need to do if follow the three easy steps below.
