How long should a counterpoise be for an end fed antenna?
How long should a counterpoise be for an end fed antenna? It is important to use a counterpoise. A standard recommendation (see QST, March 1936, p. 32, “An Unorthodox Antenna”) is an 84′ long end fed and a 17′ long counterpoise (6.5′ for 20m).
What is an EFHW antenna?
Unlike the dipole antenna, which is comprised of two quarter-wavelength wires and fed at its center, the EFHW is a half-wavelength antenna with the coaxial cable for your transceiver attached at one end. It has become popular with portable operators because it’s very simple in its construction and deployment.
What is the difference between a counterpoise and a radial?
Vertical antennas can have radials mounted on or below the surface of the actual ground. If the radial system is mounted above the ground, it is technically a counterpoise and takes the place of the actual ground.
Is longer antenna better?
Longer antennas have lower frequencies and higher bandwidths. This means signals can travel over longer distances. Radio stations operate at lower frequencies and their signals can easily connect to longer antennas.
