[TowerTalk] Antenna analyzers and parallel conductor transmissionlines

[Keith Dutson]

I would hook up a balun to that balanced feedline and use the SO239
analyzer.

Subject: [TowerTalk] Antenna analyzers and parallel conductor
transmissionlines

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,

Steve K8JQ
