FCC Technician Exam Question Of The Day (T9B03)

Q) Why is coaxial cable used more often than any other feedline for amateur radio antenna systems?

A) It is easy to use and requires few special installation considerations

NJ2X Notes:
Coaxial cable has many advantages for radio amateurs.  Here are a few:
  • Can be buried or placed on the ground
  • Can be routed in close proximity to metallic objects
  • Can be easily pulled through walls and conduit
  • Relatively low feed line loss
  • Easy on/off connectors
  • Long lasting and durable
  • Waterproof
  • Doesn't radiate (in most applications)
  • Shields the signal carried on the cable from interference
