Discover the BIG SIGNAL 6BS-270 antenna an innovative design of dual-band 144/432 MHz. With 6 elements in total, 2 active in the band of 2 meters and 4 in the band of 70 cm you will get an incredible performance guaranteed in just 70 centimeters of boom. Ideal for contacts on terrestrial (FM / SSB) and for use in communications via SAT (satellite), tested it with amazing performance.

* If this is exclusive to SAT, choose the "SAT Model" version optimized at SAT frequencies (145.8 and 435.0 MHz).

Why choose the 6BS-270 versus a traditional Yagi?

· Elements of full wavelength, reaching maximum efficiency in TX / RX.
· More gain in less boom length than a traditional Yagi.
· Less influence on the polarization crossing; less signal loss when receiving stations in different polarization. Ideal to start in satellites (SAT).
· Very low noise, which will allow you to improve the reception of weak signals in urban environments.
· Robust construction and very light weight.
· Very easy setup.

The best directional antenna option for urban environments, in times when noise in cities is increasingly high, a closed antenna is the definitive solution to improve the reception of weak signals. Welcome to the antennas without noise!

    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.
