[TowerTalk] Antenna analyzers and parallel conductor transmission lines

The antenna analyzers one finds marketed to hams all seem to have an 
SO-239 connector.

Can one use these devices with antennas fed with parallel conductor 
transmission lines such as open wire or ladder line?

If so, how do you connect the parallel conductor line to the antenna 
analyzer? One wire to the center pin and the other wire to the threaded 
body of the SO-239?

Do you lose any antenna analyzer functionality when using it with 
parallel conductor transmission line as compared to coaxial transmission 
line?

Are any particular antenna analyzers better suited to parallel conductor 
transmission lines?

Are any particular antenna analyzers favored for measuring the extremes 
of resistance and reactance (and particularly correctly indicating the 
sign of the reactance) that one encounters at the shack end of a 100ft 
dipole fed with parallel conductor transmission line operated and in the 
160 through 10 meter amateur bands?

Thanks,
