Splitter Ratio Calculator

Problem: You have a TV antenna on the roof. The main house TV is 10 feet from the splitter. The security gatehouse is 800 feet away via buried RG11 cable. Challenge: If you use a standard 50:50 splitter, the gatehouse will get almost no signal (800ft loss ~ 40dB). The house TV will be overloaded. Calculator Solution: Input cable lengths and required receive power. The calculator outputs: Use a 95:5 asymmetrical tap. 95% (0.2dB loss) goes to the gatehouse to fight the long cable run; 5% (13dB loss) goes to the nearby house.

The gold standard for modern Fiber-to-the-Home (FTTH) and GPON/XGS-PON networks. splitter ratio calculator

For a two-way splitter with a target ( C ) (0 to 1): Problem: You have a TV antenna on the roof

An asymmetrical splitter is useful when one output is very close to the source (requiring little power) and another output is very far away (requiring the bulk of the power to overcome cable loss). Challenge: If you use a standard 50:50 splitter,
