the antenna for digital terrestrial Sigma and built to the outside world, has elements of a loop geometry and a cooler with innovative design, has a very modern and Hi-tech, designed and patented by Fracarro. The setup is very easy thanks to the presence of directors, an attack on the pole and a support for the reflector. The Sigma Fracarro 6HD has 6 elements: broadband UHF antenna to receive TV, dipole with F connector, polarization H or V mounting pile up to 60 mm in diameter, dual-reflector and a curtain un'impedenza 75 ohms. As regards technical characteristics, the bandwidth is between 470 - 862 Mhz, has a maximum gain of 17 dB, a forward-backward ratio of 32db, a return loss of 18 dB and a beam width (-3dB) of + / - 18. The dimensions are 920 mm x 625mm, attack on the pole with a maximum diameter of 60mm, a wind of 120 km / h (720 N/m2) Kg (N) 23 (225.4) and a connector type F The antenna has a horizontal polarization, a zenithal horizontal adjustment, a vertical polarization and a vertical adjustment: it already included in the kit.
