The Sirio MD118-137 Aviation Antenna 118-137MHZ, Dipole 1/2 with loaded radial covering the frequency range of 118-137 MHz for the aeronautical band. The whip is made of black chromed stainless steel and all the metallic components are of brass or steel to get the best robustness. Thanks to its loaded radial MD 118-137 Aviation doesn't need any metallic ground plane and it is particularly recommended for installation on small aircraft.
Suitable for aeronautical service, omnidirectional mono-band, unity-gain recommended for installation on small aircraft flexible stainless steel radial.
Type: dipole 1/2 with loaded radial frequency range: 118-137 MHz for aeronautical band impedance: 50 radiation (h-plane): 360° omnidirectional.
Polarization: linear vertical gain: 0 dbd - 2.15 dbi max. Power (CW) at 30°c: 50 watts cable length
Materials: Stainless Steel 17/7 PH, Nylon, Chromed Brass, Zamac Wind resistance: 220 Km/h.
