Force 12, Inc. Amateur and Commercial Antennas and Towers


	Leading the way are the *Sigma Series* and they are the best verticals ever made and contest proven, with many World Records. With efficiencies between 91-99.9%, they have no equal. The *Sigma* design utilizes T-bars at each end of the vertical dipole for the most effective loading technique and on low band models, incorporates huge high-Q off-center loading coils. From 80 all the way through 70 cm, *Sigma* is the way to go! Sigma antenna's are the new evolution in verticals. They are true vertical dipoles, no radials and their performance is unmatched by any other design. They are available in several models.
