At BIG SIGNAL we present the latest generation in design and development of cubical quad antennas for the 432 MHz / 70 cm band.

Why choose a UHF cubical quad antenna over a traditional Yagi?

· 70 centimeter full wavelength antenna, 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 will allow you to reduce QRN and urban noise, improving the quality of reception of very weak signals in the band.
· Less influence to cross polarization than a Yagi. This translates into less QSB / Fading or signal loss when receiving signals in different polarization, ideal for communications via SAT or EME.
· Very high selectivity. Excellent suppression of side and rear lobes, further reducing unwanted noise in reject directions.
· Quick and easy installation, pre-assembled elements, assembly without tools.

The best UHF directional antenna option on urban environments, in times where noise in cities is increasingly high, a quad antenna is the definitive solution for DX practice with the maximum guaranteed performance.
