Delta loop 3 elementi filare reversibile
Come si comprende dal titolo, l'antenna che qui descrivo e' una classica Delta Loop a tre elementi per i 40 metri, interamente realizzata con della trecciola di rame del diametro di 3 mm

Portable HF Delta Loop
A delta loop antenna is described which is cheap, simple to make as well as being very quick and straight forward to put up for portable work. With a balanced ATU it will work well on 20, 15 and 10m
Horizontal Loop Loading Methods
The primary radiating area of a half wave loop is about 1/8th wavelength. We are essentially end loading a 1/8th wave long dipole when we use a 40 meter full wave loop on 80 meters
Delta loop 50 Mhz
A Delta loop is formed by an equilateral triangle, the base of which can lie on both the top and bottom and can be hung on various shapes
