BIG SIGNAL DL-11R
Full-Wave Rigid Delta Loop for 27 MHz DX
Full-Wave Rigid Delta Loop for 27 MHz DX
The BIG SIGNAL DL-11R is a single-band Delta Loop antenna for 27 MHz / 11 meters, developed for operators looking to improve their station's DX performance with a full-wave, horizontally polarized, closed-loop antenna.
Its unique rigid inverted-loop construction using reinforced telescopic fiberglass maintains the Delta Loop geometry without requiring multiple support points, making it an especially practical solution for permanent installations on the 11-meter band.
Band: 27 MHz / 11 meters
Type: Rigid inverted Delta Loop
Configuration: Full-wave closed loop
Polarization: Horizontal

Contento con esta Loop.
Bien construida, con buenos materiales.
Se nota la diferencia con mi otra antena vertical A99
Buen ancho de banda y trabaja muy bien en 10M también.
Thank you Big Signal for fast delivery and super support.
Antenna is fantastic, my qrm is 99% gone. RX/TX 5/9+, SWR 1.1
Simply fantastic Delta Loop.
Best 73 to you all.
Funciona muy bien los resultados en dx excelentes,la recomiendo.
Antenne très silencieuse niveau qrm je l?utilise en fixe avec de très bon résultat,fabrication de qualité.je recommande pour ceux qui veulent une polarisation horizontale à moindre encombrement
Tengo la antena BigSignal DL-11R desde hace un año. Estoy contentísimo con ella. Roe 1:1 y trabajo todo lo que oigo. Resistente al viento y colocada en poco espacio. Sin duda una gran antena y un gran servicio técnico de asistencia pilotado por Juan Pedro. Gracias por la gran profesionalidad de todo el equipo de BigSignal.
The BIG SIGNAL DL-11R really working very well, strong signal in West Indies and South of America in transmission ( with 100W) and also reception.
