Build a Multi-Band Mono Delta Loop

Make up a 14 MHz delta loop using two separate lengths of 10 meter plus 10 centimeters each of No. 12 or No. 14 stranded copper wire and connect them in series with an insulator as shown at the bottom of Fig 1. The 10 cm extra wire is passed through the end hole of the insulator then looped back to the wire element to form a splice for later soldering

Delta Loop antenna 3.5 - 30 MHz
84 m Total Wire Length (L1 + L2 + L3) - 28 m Triangle Length (L1 = L2 = L3) - 10.56 m 75ohm coaxial length

Delta Loop Lazy loop from 160 to 10 meters
The loop is 3.650 Mhz. For matching the loop on the other bands I use a Toroid Balun with

Double Half Delta DHD
In teoria dovrebbe restituire un segnale basso ma con un buon rapporto S/N, pressappoco come una Beverage. L' antenna e' costituita da due triangoli di filo sospesi a un metro e mezzo da terra


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

Atu balanced feeder antenna system

Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
