  Using the first station of the Long Wavelength Array (LWA1), we examine
polarized pulsar emission between 25 and 88 MHz. Polarized light from pulsars
undergoes Faraday rotation as it passes through the magnetized interstellar
medium. Observations from low frequency telescopes are ideal for obtaining
precise rotation measures (RMs) because the effect of Faraday rotation is
proportional to the square of the observing wavelength. With these RMs, we
obtained polarized pulse profiles to see how polarization changes in the 25-88
MHz range. The RMs were also used to derive values for the electron density
weighted average Galactic magnetic field along the line of sight. We present
rotation measures and polarization profiles of 15 pulsars acquired using data
from LWA1. These results provide new insight into low-frequency polarization
characteristics and pulsar emission heights, and complement measurements at
higher frequencies.
