Hello Jeff,

Because of the length involved, most people on 6m simply use coaxial power
dividers. To do this, you just use a coaxial T connector in the middle of the
power divider. If you are making a 2 way power divider, you simply connect a 1/4
wavelength section of 75 ohm coax to each side of the central T connector. The two
50 ohm phasing lines are connected to the ends of the 1/4 wavelength pieces of 75
ohm coax.

If you are making a four way coaxial power divider, the 1/4 wavelength pieces of
coax should instead be pieces of 50 ohm coax, with a T connector on each end (so
two antennas can be connected to each end). As with the 2 way coaxial power
divider, the 1/4 wavelength long power divider pieces can also be lengthened to
any ODD multiple of 1/4 wavelength (3/4,5/4, etc.) You must use something like an
MFJ-259 Antenna Analyzer to make sure that the coax pieces are exact odd
ELECTRICAL multiples of 1/4 wavelength.

Here is the information from my web page on how I built my 4 way 6m power divider:

The 4 way 1/2 wavelength power divider was built from 1.25" OD square aluminum
tubing with a .125" wall thickness. The inner conductor was 15/32" OD round hobby
brass tubing, creating a line impedance of 50 ohms. Four .375" thick teflon
spacers were evenly spaced at approximately 20" intervals (between the spacers or
RF connections) through the inside of the square tubing, to keep the center
conductor supported and centered. The overall length of the aluminum tubing for
the power divider was 10', with 57.75" (using a velocity factor of .98) from the
center connector to the point where each pair of N connectors were connected.
(Next time I suggest using a velocity factor of .975, since the low end of the 6m
band was just on the upper end of the bandwidth for a perfect match with the
device built as described above). The connector for the main feedline was a 7/16
connector, to insure plenty of extra durability in terms of handling RF power.
The flexible coax around the rotator was LMR600 ultraflex, with 7/16 connectors on
both ends.

I don't know why you would want to build a 2-way power divider using square
aluminum tubing (rather than the much simpler method of using 75 ohm coax), but
you would just follow the recipe above, but make the inner conductor smaller, to
make the "hardline coax" have 75 ohms impedance. If you are interested in making
one this way, you can use this information to pick appropriate sizes of square
aluminum tubing and round brass hobby tubing:

For 75 ohms, you would want a ratio of about 4.5375 between the round inner
conductor OD and square outer conductor ID. With a 1" ID square aluminum tubing,
that means .2204" OD brass hobby tubing, or 7/32" OD.
