Folded Dipole for 40m
This Antenna model is ideal for those who do not have much space available and do not want to use vertical or coiled antennas

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
We are going to use an 80 meter 1/2 wave dipole for this discussion.An 80 meter dipole 3.8mhz is about 38.5 meters 126.3feet total length
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
