BIG SIGNAL SkyLoop-46
High-Performance Omnidirectional Loop for 50 and 70 MHz
High-Performance Omnidirectional Loop for 50 and 70 MHz
The BIG SIGNAL SkyLoop-46 is an omnidirectional antenna designed for the 50 and 70 MHz / 6- and 4-meter bands, offering a simple and efficient solution for operators who want to explore DX without installing a directional antenna.
Its closed-loop design combines dual-band operation, horizontal polarization, and favorable weak-signal reception characteristics, making it an attractive alternative to conventional verticals, dipoles, and other omnidirectional antennas.

A Simple Way to Explore DX on 4 and 6 Meters
The 50 and 70 MHz bands can produce remarkable propagation openings and long-distance contacts. The SkyLoop-46 allows you to take advantage of these conditions with an omnidirectional antenna that is simple to install and operate, without having to continuously point a directional array.
It is especially well suited for operators looking for a practical antenna to monitor band openings, receive weak signals, and begin working DX on both bands.

Buenos días. Instalada este fin de semana. Efectivamente sorprende el bajo ruido (en comparación a la Ringo de 1/2 onda que tenía para 50 mhz) y sobre todo el ancho de banda con ROE mínima en ambas bandas). Ayer domingo hubo una apertura interesante en 50 donde tanto en FT8 como fonia se podia trabajar prácticamente todo lo que se oía. En 4m menos actividad y sólo FT8.
Esta antena no la he probado, pero estoy que dará muchísimas alegrías. Conozco éstas antenas desde hace mucho tiempo, tengo 6 antenas entre monobandas de 2 m hasta multibandas y en cada contacto siento que tengo una antena poderosa. Nunca recomiendo nada a nadie, porque ya sabemos que cada equipo, cada situación, cada instalación etc etc son diferentes y los resultados son múltiples, pero en caso de antenas siempre BIG SIGNAL.
Un saludo a todos.
Estoy encantado con la antena, en cuanto a la instalación y montaje muy sencillo, es una antena que pesa bastante poco, la he colocado a una altura de 2mts sobre la cubierta. Luego de instalarla he podido de disfrutar de apertura en 6m, muy bien. Y ayer mismo apertura en 4m de apenas 45 minutos con 19 contactos, muy bien también.
