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
Short Antenna per le HF
L'antenna e fatta da 3 parti, la parte radiante con la sua capacita

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
