Antenna Factor and Gain Calculations

Antenna Factor and Gain metrics provide crucial insights into antenna performance, allowing engineers to calculate signal strength relationships and directional effectiveness. These measurements help optimize RF systems by comparing actual antenna behavior to theoretical isotropic radiators using standardized 50-ohm configurations.

This first edition of the Standard for Power-Operated Pumps for Diesel Fuel, Biodiesel Fuel, Diesel/Biodiesel Blends with Nominal Biodiesel Concentrations up to 20 Percent (B20), Kerosene, and Fuel Oil, ANSI/UL 79B, covers electrically-, hydraulically-, or pneumatically-driven power-operated pumps for use with petroleum products.
