Engineering:Relative directivity factor
From HandWiki
Short description: Formula for calculating signal to noise ratio
Relative directivity factor (RDF) is a figure of merit for radio receiving antennas.[1] It is the antenna gain in the forward direction divided by the gain in all other directions. It is also called the signal to noise improvement factor (SNIF).[2]
