Josh, I thought you meant you were just cutting it off. Sorry... I'm an antenna engineer.

The main importance in the Sleeve Dipole is in transmitting the telemetry back. it prevents standing wave reflections in the coax by acting as a balun. (BALanced to UNbalanced) transformer. In just the receive function the difference would be small.

See the 3 drawings here for how a sleeve works.
