BIG SIGNAL SpaceQuad
The handheld revolution for satellite operations is here.
At BIG SIGNAL, we're committed to bringing you the latest innovations in amateur radio antenna technology. Today, we’re proud to introduce a true game-changer: the BIG SIGNAL SpaceQuad, the first-ever handheld portable quad antenna for V-UHF on the market.
Why choose the SpaceQuad?
Because it’s built by hams, for hams—engineered for real performance, portability, and simplicity, without compromise.
· Ultra-lightweight: Weighing just 430 grams (15 oz), the SpaceQuad is light enough for effortless one-handed operation, even during long satellite passes.
· Compact and clever: With a boom length of only 56 cm (22 inches), it's the world’s first portable quad for satellites. Small in size, big in performance—perfect for working any active SAT, anywhere.
· Fast, tool-free assembly: Tired of wasting time setting up bulky Yagi antennas? The SpaceQuad is fully assembled and ready in under 5 minutes, with no tools required. Spend more time on the air, less time preparing.
Performance that outshines the traditional
Optimized for satellite segments at 145.8 and 435.5 MHz, the SpaceQuad features:
-
2 full-wave quad elements on VHF.
-
4 full-wave quad elements on UHF.
With a true 50 Ohm design, no impedance matching or baluns are needed. This means maximum efficiency, minimal losses, outstanding gain, and a wide bandwidth—all in one compact package.
And here’s where the SpaceQuad truly stands apart: unlike traditional Yagi antennas, its quad design provides superior resistance to polarization shifts and significantly reduces signal fading (QSB). Enjoy more stable signals without constantly adjusting wrist angles during passes.
Take it anywhere. Operate anytime.
With its smart design, extreme portability, and high-end performance, the SpaceQuad is your ideal companion for handheld satellite operations.
- Why stick with the same old antennas, when you can step into the future?

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!
