Antenna 40 Meter Links →
Shortened with 40 turns trap 7 mhz Dipole
To construct each side of the antenna proceed as follows. Cut a 10.25 metre length of 24/0.076 insulated wire, and a 160 mm length of 40 mm o.d plastic tubing
Shortening your dipole
Loaded dipole antenna that is intended to fit in available space
Sloper sloping dipoles 40mt-80mt
Having only a single vertical support or limited horizontal space might be a problem.Such a problem can be solved by mounting a dipole at a slope
Super gain antenna project for 40 meters
It is based on the theory of super gain NVIS arrays, which reject QRM from low angles and produces a very high angle of radiation

Noise suppression with X-phase II This device similar devices are known as QRM eliminators or noise killers, makes it possible
The K9AY loop antenna for 160 and 80m bands You don't have the space to put up a 4 beverage antenna's, an ewe or a 4-square and want 'good ears' on 160 and 80m? no problems try a k9ay loop antenna
