In just 40 centimeters of boom, our 2 element Quad antenna for VHF BIG SIGNAL 2BS-2 is able to offer a gain of 7.8 dBi at the front.
The perfect antenna for a small VHF directive of high performance in a super reduced space, as well to be active in /Portable, SOTA, EMCOM etc. since its small size makes it transportable even mounted without major difficulty.
Main characteristics compared to other beam antennas:
· Elements of full wavelength, reaching the maximum gain and performance. · Attenuation of the QRM, improving the reception of weak signals in urban environments. · Extraordinary rejection/lateral, providing high directionality and reducing noise in the rejection directions. · Very low radiation angle even at low height, essential for the DX. · Only 0.40 meters boom and reduced turning radius, ideal for small spaces. · Very robust construction with high quality materials, with a super light weight.
The best directional antenna option for urban environments, in times when QRM in cities is steady increasing. This closed antenna is the ultimate solution to improve DX reception.
