Radio luminosity of high-z quasars compared to known radio galaxies (purple diamonds; Saxena et al. 2019) and SDSS DR16 quasars detected in LoTSS-DR2 between 2 < z < 5 (grey circles) as a function of their redshift. The grey shaded area indicates the 5σ detection limit of LoTSS and the filled blue circles are quasar detections at a > 2σ level. Radio luminosities corresponding to 0.8 mJy and 8 mJy at 144 MHz are indicated with red dashed and solid lines respectively. The triangles indicate upper limits for quasars with < 2σ detection.
