What is the primary use of a Beverage antenna?

  1. Directional receiving for MF and low HF bandsپاسخ درست
  2. Directional transmitting for low HF bands
  3. Portable direction finding at higher HF frequencies
  4. Portable direction finding at lower HF frequencies

A Beverage is a long wire strung low over ground, terminated at the far end, giving a strongly directional and quiet pattern at MF and low HF. Its proximity to lossy ground makes it extremely inefficient, so it is used for receiving only.
