Power splitters are used to
feed an antenna array with a 50 ohm cable. The impedance of the power splitter is computed with the following formula
where Za is the impedance of the antenna array, which
depends on the number of single yagi put togheter; with two yagi
the impedance is 25 ohm, while with four it is 12.5 ohm, thus:
Two other formulas are used to compute the size of the power splitter.
First formula is used with round tubes and the latter for a
square external tube (the internal one is always round).
where D is the internal diameter of the external tube and d
is the external diameter of the internal tube. Line lenght is
lambda/4.
