In BIG SIGNAL, we take pride in introducing to you the latest innovation in the design and development of Cubical Quad antennas for the 432 MHz / 70 cm band, including our flagship model with 22 elements, the BIG SIGNAL 22BS-70, the largest model in our catalog for the 432 MHz band.
Why should you choose a UHF cubic antenna over a traditional Yagi?
·Our full-wavelength antenna at 70 centimeters is synonymous with maximum performance and efficiency.
·It offers higher gain in a smaller boom length compared to an equivalent-sized Yagi.
·Experience minimal noise levels. Thanks to its enclosed design, this antenna significantly reduces QRN and urban noise, enhancing the reception quality of extremely weak signals in the band.
· It's much less susceptible to interference due to polarization cross-polarization compared to a Yagi. This results in a noticeable reduction in QSB, fading, or signal loss when receiving transmissions with different polarizations, making it ideal for satellite communications or moonbounce as well.
· It provides exceptional selectivity, with impressive sidelobe and backlobe suppression, further eliminating unwanted noise in undesired directions.
· Installation is quick and easy, with pre-assembled elements and tool-free assembly.
In an urban environment where noise continues to increase, our Quad antenna becomes the ultimate solution for achieving DX with guaranteed performance.
