Coaxial antenna cable with extremely low loss, even better as H155 and AC5.
The high degree of flexibility and the relatively small outer diameter facilitate the installation considerably.
Especially fire-retardant and halogen-free insulation, very resistant to radiation. Most suitable cable for connecting to VHF, transponder and anti-collision (Flarm) equipment.

*Only crimp coax connectors can be used, clamp coax connectors don't fit*
