Ronja Signal Cabling Material

Where do I get the material?

Electrician

• Two lengths of shielded coaxial cable(not necessarily high-frequency one). May be also one length of double coaxial cable (molded together from factory). Requirements:
  • Weatherproof. Otherwise Ronja has to be installed behind a window. Or the cable must be in the whole run installed in plastic skirtboard or in a flexible plastic wiring conduit. The ends and transitions of these protectors must be sealed against accumulation of water inside.
  • Length according to distance between AUI Forte/Twister and optical heads
  • Both inner wire and outer wire must be solderable
  • Stranded wire is preferred for the inner wire. Hard wire increases the risk of breaking
  • If the inner wire is a hard wire, it must not be plated (galvanized).
  • Interwoven shielding is preferred to spiral one
  • Other type of cable, especially UTP or STP, is not allowed!

  Maximum length is specified according to the table:

  Cable type	Maximum length	Installation
  low-frequency (audio) shielded double or single coaxial cable, 2mm (or 2mmx4mm if double) outer diameter	Do not use at all
  low-frequency (audio) shielded double or single coaxial cable, 3mm (or 3mmx6mm if double) outer diameter	30m	Indoor only
  high-frequency (radio) coaxial cable, 3mm outer diameter	50m	Indoor only
  high-frequency (radio, tv, or evene wifi) coaxial cable, 6mm (or 3mmx6mm if double) outer diameter	100m	Outdoor, lifetime limited to approx. 5 years
  high-frequency (radio, tv, or evene wifi) coaxial cable, for outdoor installations	100m	Outdoor

  If cable is not for outdoor, shall go mainly indoor and partially outdoor, placing it into protective plastic sheath (gooseneck) is highly recommended. If the cable path is longer than 30m, double HF coaxial must be used (RG58 or radio or TV coax).
• 2.1m of coaxial cable. The same requirements apply as to above long coaxials.
• 1m of insulated flexible single-conductor with >= 1mm^2 crosssection
• 0.5m of 4mm^2 hard copper wire, insulated
• Solderable eyelet with hole for M6 bolt
• Duct tape - black, red, blue
• Rosin flux
• Solder
