2 Elements 20m Delta Loop
For this project I started describes the building of a HF three bands 10-15-20 aluminium delta loop, but I limited the design to 20m band only

Delta Loop Dimenciones de la Antena en Mts
Delta arms, are all corticircuitados each other, the impedance at the point of power is 120 ohms, for this reason to feed it, a Much Range adapter is used. It is ideal for bands of 10, 15 and 20mt
Delta loop for 20mt
L'elemento radiante e' un triangolone di 6,7 metri per lato per un totale di 20,10 metri ed al centro della base del triangolo, realizzare un bobina fatta di 16 spire in aria diam. 2 cm., lunga 10 cm
28 and 24 MHz Limited Space 3/4 Wave Delta Loop
Using the standard formula for loops, 1005 divided by frequency in MHz gives us the one-wavelength design length for a particular band

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
