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.
