Probably the best DX site in the world DX news How different antennas can battle external noise. Why I should use a loop antenna. Buried antennas for areas with restrictions. How long a Beverage antenna should be.
Active antenna can overcome local interference.
Go for the Snake. Find the optimum antenna height for a dipole. Design engineers go to great lengths to maximize efficiency, minimize mismatch to the feedline, and maximize radiation in the direction of the horizon with as little upward radiation as possible for maximum distance per hop. We will look at the applicability of these concepts for the SWL and explore why you may want to adopt totally different approaches for your DX receiving antenna. We will show why antennas close to the ground work well for receiving.
