[Moon-net] 2m 2x2 Power Splitter

[Andreas Haefner]

Hi Tom.

why don't you build this power splitter on your own ?
Its very easy. Z of this Line is 50 Ohm because you make
transformation from 25 Ohm on each side to 100 Ohm in the middle.
There are 2 x 100 Ohm Lines in parallel is again 50 Ohms
in the middle.

You can use the following combinations:

copper tube 8 mm  
alu square  20x1.5 mm = 49.7 Ohm

copper tube 10 mm
alu square 25x2 mm = 49 Ohm

copper tube 12 mm
alu square 30x2 mm = 50,9 Ohm

copper tube 15 mm
alu square 35x1.5 mm = 50 Ohm

Length is 1040 mm = 2 x 90 degrees on 144.3 MHz
