In BIG SIGNAL have the last generation in the design and development of Quad antennas for 144 MHz/2 m.
Why choose a Quad antenna versus a traditional Yagi?
· Full wavelength antenna in 2 meters, achieving maximum performance and efficiency. · More gain in less boom length than a Yagi of the same size. · Very low noise. Being a closed antenna, it will allow you to reduce the QRN and improve the reception quality of weak signals in the band. · Less influence to the polarization crossing. This results in less QSB or signal loss when receiving signals in different Horizontal / Vertical polarization. · High selectivity. Excellent suppression of lateral and rear lobes. · Robust construction for extreme durability.
