Is it safe to use DIY CB antenna if the SWR is under 1.5 and can you use longwire antenna for receiving CB radio?

A standing wave ratio of 1.5 is still a bit high. You should couple the antenna via some sort of antenna tuner and tune as close to 1:00 SWR. While t is possible to use a longwire antenna for CB reception purposes, the performance won't be too great. If, however, you are planning on transmitting, again, the longwire antenna should be coupled to the transmitter via some form of antenna tuner, to match impeadances, lower the SWR, and protect the final stage of the transceiver. A resonant long wire antenna only requires that the length of the wire is approximately resonant at the frequency of operation. For CB this means the wire must be a multiple of 11.1m (36ft 6.5 inches). Therefore, a three wave long wire would be 33.3 m (109' 9") and four-wave long wire would be 44.4m (146' 3") in length.
