Sirio Gainmaster Base Station Antenna


  • 12m band covered with manual or automatic antenna tuner.
  • Type: 0.625 center feeded vertical dipole
  • Frequency Range 25.5 – 30 MHz wide band from 10m to 12m* ham band
  • Impedance 50 ohm
  • Radiation Omnidirectional
  • Polarization Linear Vertical
  • Max Gain on the horizon 1 to 2 dB higher than conventional 5/8
  • Max Power 500 Watts (CW) continuous, 1000 Watts (CW) short time
  • Lightning protection
  • All metal parts are DC grounded, the inner conductor shows a DC-short
  • Completely computer designed, it’s made and assembled entirely in Italy
    with the finest materials available, starting from the whip which is carried out
    in four sections of 1.92m telescopic tubes with triple-layer fiberglass; it makes
    Gain-Master™ much more durable and rigid then the competitors.

Gain-Master™ is a 0.625 high tech fiberglass
base station antenna for wide band antenna from 10m to 12m*
amateur band

Completely designed by electromagnetic simulation to achieve the
maximum gain and optimize the radiation pattern and bandwidth.

Engineered with the most advanced available technologies it is
completely manufactured in Italy with high quality materials.

The new design of the radiant element (Patent Pending) works
like a central feed dipole so all RF currents on the radiator are
in-phase and the ground plane radials are not necessary.

The coaxial coil at the bottom works like RF-choke for the optimum
decoupling from mast and feeding line.

Made of telescopic fiberglass tubes, it is DC-grounded for the best
protection from static discharges.

Gain-Master™ is the new reference standard in its class of antennas.
