▼Never use the cigarette lighter socket as a DC source.
▼The entire length of the cable must be dressed so it is isolated from

Before operating, install an efficient, well-tuned antenna. The success
of your installation will depend on the type of antenna and its correct
installation.
Use a 50Ω impedance antenna and low-loss coaxial feed-line that
an impedance other than 50Ω reduces the efficiency of the antenna
system and can cause interference to nearby televisions, radio receivers
and other electronic equipment.
