The BIG SIGNAL – Antenna Systems company has a radio amateur background, Juan Pedro, EA5GJ. The company also cooperates with the well-known Máximo EA1DDO. They specialize in loop antennas and quad smerové antény v rozsahu 3,5 až 432 MHz.
Quad antennas are known for their excellent electrical properties. BIG SIGNAL antenna designs are optimized and simulated using state-of-the-art software. Then each model was subjected to direct testing and verification directly in operation.
V priebehu rokov antény Cubical Quad a Delta loop vyvolali veľké pochybnosti o ich mechanickej pevnosti a životnosti. V súčasnej dobe so zlepšením materiálov sa mýty o ich krehkosti zmenili a sú históriou.
