Abstract

Radio frequency feed line for connecting an HF radio tuner to a tunable antenna. Radio frequency feed line (1) for connecting an HF radio tuner to a tunable antenna, with a length between 0.7 m and 3 m, comprising: a central conductor wire (2); an electrically insulating sheath (3) surrounding the conductor wire (2); an electrically insulating layer (4) comprising nested frustoconical eyelets (4a) with a maximum radius between 2 and 3 cm; a heat-shrinkable sleeve (5) encasing the electrically insulating layer (4); and two self-amalgamating sleeves (6) at both ends of the electrically insulating layer (4).
