At BIG SIGNAL, we're leading the way in designing and developing the latest Cubical Quad antennas for the 70 MHz / 4 m band.
Why choose the 4BS-4 antenna over a traditional Yagi?
· Full wavelength antenna at 4 meters for maximum performance and efficiency.
· More gain in less boom length compared to a traditional Yagi antenna.
· Noise reduction: Its closed design attenuates QRM and improves the reception of weak signals.
· Very low radiation angle, even at low altitude: Fewer hops to reach DX, resulting in a stronger signal.
· Robust construction with high-quality materials for extreme durability.
