Abstract: Giant double-lobed radio source 4C34.47 displays a straight one-sided jet,measuring a record length of 380kpc, in its double-lobed radio structure.Assuming an intrinsically symmetric two-sided jet structure the radio sourcejet axis must be at least 33 degrees away from the sky plane, that is within 57degrees from the line of sight. The radio polarization properties indicate thatthis giant source has largely outgrown the depolarizing halo generallyassociated with the host galaxies of powerful radio sources. The measured smalldepolarization asymmetry is nevertheless in accordance with its inferredorientation. All data for this giant radio source are in agreement with itspreferred orientation as predicted within the unification scheme for powerfulradio sources. Seen under a small aspect angle the radio source is large butnot excessively large. The global properties of 4C34.47 do not differ fromother giant old FR2 radio sources: it is a slowly expanding low-luminosityradio source.
