Using the 26-m single-antenna telescope of the DRAO a new survey of linear polarization (Stokes U and Q) of the northern sky at a frequency of 1.4 GHz has been carried out. The angular resolution is 36 arc min. The data are absolutely calibrated and corrected for ground radiation. Observations were carried out by drift scanning the sky between +90 and -29 degree declination. With an integration time of 60 s per 15 arc min interval in R.A., a bandwidth of 12 MHz, and a system temperature of about 158 K the rms-noise in U and Q is 12 mK. The total sky coverage is 41.7%. Stokes U and Q maps are available for research and education.
