BIG SIGNAL SpaceQuad
The handheld revolution for satellite operations
Meet the BIG SIGNAL SpaceQuad — the world’s first handheld portable quad antenna for VHF and UHF. Designed by hams, for hams, the SpaceQuad redefines what’s possible in portable satellite operations: real performance, extreme portability, and unmatched simplicity.
Key advantages
· Ultra-lightweight: Only 430 g (15 oz) for effortless one-handed operation, even during long satellite passes.
· Compact & clever: With a boom length of just 56 cm (22 in), the SpaceQuad is the world’s first truly portable quad for satellites. Small in size, big in performance — perfect for working any active SAT, anywhere.
· Fast, tool-free setup: Fully assembled and ready in under 5 minutes. No tools. No hassle. Spend more time on the air, not setting up.
Performance that outshines tradition
Optimized for satellite segments at 145.8 MHz (VHF) and 435.5 MHz (UHF), the SpaceQuad features:
· 2 full-wave quad elements on VHF
· 4 full-wave quad elements on UHF
With a true 50 Ω design, no impedance matching or baluns are needed. The result: maximum efficiency, minimal loss, and excellent gain — all in a compact, lightweight antenna.
And unlike traditional Yagis, the quad geometry offers superior polarization stability and dramatically reduces signal fading (QSB). Enjoy steady, reliable signals without constantly twisting your wrist during satellite passes.
Take it anywhere. Operate anytime.

Después de cinco años buscando y probando distintas antenas, ¡por fin he encontrado una que realmente funciona en condiciones extremadamente exigentes! Estoy encantado con la Big Signal SpaceQuad: no solo ofrece un rendimiento sobresaliente, sino que además es increíblemente ligera y prácticamente inmune al viento cuando se sostiene a mano.
Aquí, en Märket Reef, donde el viento rara vez baja de los 7 m/s y a menudo supera los 10 m/s, cada gramo y cada forma cuentan. Esta antena ha superado todas mis expectativas: es fácil de manejar, resistente a los elementos y está diseñada para operadores que necesitan portabilidad sin renunciar al rendimiento. Por fin, una solución fiable para condiciones extremas
After five years of searching and testing different antennas, I?ve finally found one that truly works in extremely challenging conditions! I?m thrilled with the Big Signal SpaceQuad?it not only delivers outstanding performance but is also incredibly lightweight and practically unaffected by wind when held by hand.
Here at Märket Reef, where the wind rarely drops below 7 m/s and often exceeds 10 m/s, every gram and every shape matters. This antenna has exceeded all expectations: it?s easy to handle, resistant to the elements, and built for operators who need portability without sacrificing performance. Finally, a reliable solution for extreme conditions.
Antena con una excelente oreja y fácil de transportar. La uso principalmente para dispersión meteórica y DX en VHF. Montada sobre un trípode dentro de casa junto a la ventana con horizonte este-sur.
La recomiendo para quien necesite una solución fácil de montar y desmontar, ligera, sin apenas QRM muy útil en barridos con equipos SDR desde la ciudad.
Tuve el privilegio de probar una unidad en Iberradio como AO1IBR, por gentileza de Juan Pedro, EA5GJ.
Es una pequeña GRAN ANTENA, la utilizamos en varios pases de diferentes satélites, pero la prueba de fuego fue en el JO-97, en un pase rozando al horizonte (7 grados de elevación máxima), y casi detrás de algunos edificios! Llegábamos al satélite sin problemas!
Es muy ligera, y al ser el boom corto, el centro de gravedad no está lejos de la empuñadura, por lo que no se siente ningún tipo de fatiga en lo que dura un pase.
En fin materiales de primera calidad y una vez desmontada (se monta y desmonta en pocos minutos), "casi" cabe en un bolsillo. ;-)
100% recomendable!
