Looking for a small beam antenna for V-UHF? 

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.

    Solo puedo estar de acuerdo con Jacco. ¡Qué antena tan increíble! La uso para satélites con resultados fabulosos. Perdón si molesto a los fanáticos de la ARROW, pero esta pequeña la supera incuestionablemente. Cuando recibí la antena estaba lloviendo a cántaros, así que la configuré para probar en mi invernadero. Podría recibir de horizonte a horizonte hasta 2 grados y eso en el interior. Incluso trabajé a 2M0SQL Peter en los pájaros lineales y de FM. Una buena antena, vale el dinero que pagué. Bien hecho muchachos.

    I can only agree with Jacco on this one. What an amazing antenna!!! I use it for satellites with fabulous results. Sorry to upset arrow fans but this little beauty beats it hands down. When I received the antenna it was pouring with rain so set it up to test in my conservatory. I could receive from horizon to horizon down to 2 degrees and that indoors. Even worked 2M0SQL Peter on the linear and fm birds. A good antenna worth the money I paid. Well done guys.

    The performance is amazing on 2 meters. I manage to make a contact about 300 km away while almost surrounding with high buildings. I also used the antenne for sat operation. I have made 3 contacts so far.
