New Groundmounted 80m 4 square
The thre lower alloy poles are 15m tall in total. Plus the 6 spoke capacity hat 6x 140cm I was resonant at 3800 khz. Maybe when I add the perimeter alloywire around the 6 spokes I will be at 3750

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

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
