Coax Info

Information sourced from Coax Data and ML&S

Prices sourced from ML&S inc. VAT

Diameter RF Loss Max Power Handling Cost Datasheet
mm dB/100ft @ 400MHz W @ 50MHz (1:1 SWR) /25m Reel
RG-58 5 10.5 450W £20.70
RG-213 10.3 4.5 1500W £32.25 http://www.romkatel.ro/cataloage/pdf/eupen/RG213.pdf

Note: Connectors for Ultraflex 7 are uncommon, and so may add significantly to the expense.


Lightning Precautions

  • Talk to E&F about:
    • Current mast situation
    • Building requirements
  • Can we rely on lightning path through the rotator body?
  • Kit will be toast whatever happens, priority is mitigating fire risk.


Static Protection

  • Resistive bleeders on all coax
