The PMG experiment uses somewhat different hardware from the Seds deployer, although it is for the most part built by the same groups. The PMG tether remained attached to the Delta stage.

PMG was launched with a 500m conducting tether containing a copper cable. The tether deployer and end mass contained a xenon gas dispenser to complete a 0.1 kV electrical circuit through the tether with a 0.3 amp current, in a 6-hour experiment to study space tethers' electrodynamic properties.
