At BIG SIGNAL we present the latest generation in design and development of Cubical Quad antennas for the VHF / 144 MHz band.
Why choose a Quad antenna versus a traditional Yagi?
· Full wavelength antenna in 2 meters, reaching 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 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 directional antenna option for 144 MHz on urban environments, in times where noise in cities is increasingly high, a cubical quad antenna is the definitive solution for DX practice with the maximum guaranteed performance.

Dear Radio Amateurs.
I am happy for the decision to buy the 8 ele. Quad Antenna for the 2m Band.
Now I am able to hear stations, that I have never heard before. You can try it. Iam sure, that this is the first 8ele. Quad antenna, now working in Carinthia-Austria.
With the very best regards
