Ken,
About your tuner, it does have the cable RF choke like the original paper
shows?
Although not a "balun", that does choke off RF current from the outside of
the shield of the input coaxial connection to the rig.  The original paper
is quite correct about using a solenoid wound coax cable as the optimum
coaxial cable choke, and not scramble winding coax.

However, I wonder if the most compact and equally effective 1:1 cable choke
is not the use of cores on the length of coax, which then can be about 14
inches or less, (depending on the cores used).
