BIG SIGNAL DL-11
Full-Wave Delta Loop to Take 11-Meter DX to the Next Level
The BIG SIGNAL DL-11 is a monoband full-wave Delta Loop antenna specifically designed for operators looking to get the most out of the 11-meter band with a simple, efficient wire antenna engineered with DX performance in mind.
Its closed-loop geometry, horizontal polarization, and easy installation provide a high-performance alternative to more conventional wire antenna configurations, with the added advantage of requiring a support mast of only approximately 5 m (16.4 ft).

What Makes the DL-11 Different?
• A Full-Wave Loop for 11 Meters
The DL-11 uses a full-wave closed-loop element specifically dimensioned for the 11-meter band, utilizing the entire electrical length of the loop.

• Excellent Signal-to-Noise Ratio
The closed-loop geometry can provide cleaner reception in the presence of certain types of electrical noise, an especially useful advantage when trying to copy weak signals from urban and electrically noisy locations.

• Performance Beyond Conventional Half-Wave Designs
Compared with configurations such as half-wave dipoles and certain conventional wire antennas, the DL-11 uses a full-wave closed-loop radiating element and provides an attractive combination of gain, efficiency, and signal-to-noise performance.

• No Tall Support Required
The DL-11 is designed to be installed with a support point starting at approximately 5 m (16.4 ft) high, making it a practical option for locations where a taller antenna installation would be difficult.

Designed to Hear the DX Just Above the Noise Floor
On 11 meters, good receive performance can be just as important as the signal you transmit. The DL-11 combines horizontal polarization with closed-loop geometry to provide an antenna particularly well suited for working weak DX signals.
Why Choose a Delta Loop for 11 Meters?
A conventional dipole uses a radiating element approximately one-half wavelength long. The DL-11 uses a full-wave closed loop, providing a different geometry and radiation pattern.
The result is an antenna for operators looking for more than simply putting a signal on the air: better reception, making the most of propagation openings, and enjoying serious DX on 11 meters.

Perfecta ruido irrisorio, permitiendo tener un oreja mas grande en DX. La he instalado de modo fijo justo debajo de la antena vertical Sirio 2016 y queda de miedo, estoy satisfecho de la calidad y acabados de 10.
Totalmente recomendable y de una tamaño mas que razonable.
Excellente antenne, que j'utilise essentiellement depuis mon QRA en agglomération en mode ROS (27.635) avec des résultats exceptionnels que je n'ai jamais réalisé avec une autre antenne.
Bravo à Bigsignal pour sa compétence et la qualité du matériel proposé.
Una antena excepcional para operaciones en Portable..

Corroboro todo lo escrito por los compañeros que han opinado sobre esta antena y tan solo quiero remarcar que es una excelente antena, con un magnífico comportamiento tanto en RX como en TX montaje muy sencillo y rápido y sobretodo quiero felicitar al equipo de Big Signal por el esmero con el que tratan sus productos, los cuales son de una gran calidad. También quiero decir que la
atención de su personal es simplemente perfecta

Una antena excepcional para operaciones en Portable, la use en varias expediciones y siempre se comportó de 10.
Además que no necesita de mucha altura, y la ROE 1:1 en toda la banda, recomendada al 100%
Nos oímos al otro lado del PileUP 59+ ;-)
Si te lo quieres pasar bien en portable y tardar poco tiempo en montar una antena y no llevar herramienta no lo pienses esta antena . Yo la tengo y hay videos que lo demuestran que el ruido que tiene una vertical esta antena no lo tiene y eso es muy bueno porque con la vertical una señal muy baja no la puedes hacer el comunicado y con esta Delta loop si . Estoy muy contento y resistencia al aire no tiene y no pesa nada .
Compré una BIG SIGNAL DL-11 para portable y la coloque en una caña de pescar de 9 metros. Desde el primer día que la probé quede maravillado, no necesite ajustarla, es mas al principio pensé que la había colocado mal ya que no había nada de QRM. En cuanto empecé hacer los primeros contactos tanto a nivel nacional como de Europa los controles de señal que me daban eran muy altos para la poca propagación que había y la recepción era muy buena. Para probar hice una comparación con una antena vertical que yo tenia una Sirio 827 5/8 y la verdad ni comparación la recepción era más baja y el QRM mayor.
Comparándola con una Sirtel 1.200 de móvil y una Solarcom Imax 2000 de base superando a las dos en RX & TX y bajando los niveles de QRM e incluso el QSB.
