Discover our BIG SIGNAL 6BS-270 model, ideal for getting started in satellites or terrestrial contacts (SSB/FM) with only 70 centimeters of boom, but which guarantee incredible performance with 2 active elements in VHF and 4 elements in the UHF band.
Why choose the BIG SIGNAL 6BS-270 antenna over a traditional Yagi?
· Full wavelength antenna in 2 meters and 70 centimeters, 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 bands. · Less influence to the polarization crossing. This results in less QSB or signal loss when receiving signals in different Horizontal/Vertical polarization. · Extremely wide radiation lobes, ideal for starting on SAT without lifting rotor
The best option on the market in relation to quality / price with antennas with similar characteristics.
