The most modern technology and the most advanced instruments have been used for realizing Sirio 827, the new 5/8 base station antenna made of large diameter Silicium Magnesium alloy tubes to give the maximum strength. The ground plane is composed of 8 aluminium radials which allow a perfect radiation pattern and the coil, made of high guace enemmaled copper wire, has been especially designed to handle high powers. Sirio 827 does not need any tuning because it's pretuned, however, fine adjustment can be made by acting on the final top whip. Technical Data Type 5/8 Ground plane Impedance 50 Frequency range 26-29 MHz Polarization vertical V.S.W.R. 1.1:1 Max. Power 2500 Watts Bandwidth 2500 KHz Gain 7.5 dB Connection UHF PL 259 Length (approx.) 6.85 mt Weight (approx.) 5.00 kg Mounting mast 35/40 mm
