[Moon-net] 2m 2x2 Power Splitter

[Kjell Jarl]

Hi,
For the purpose of matching four 50 ohm loads to 50 ohm over a narrow 
band, I find it easier to just use koax.

The coax power splitter does exactly the same as the ones described 
elsewhere.

I use N male connectots for the two 1/4-wavelength pieces (lengths 
include the distance to the centre of the Tees), and N female 
T-connectors (three).

It works for me.
