Sirio GainMaster Antenna

The NEW GAIN MASTER by SIRIO is a high tech fiberglass base station antenna for CB and 10m amateur band. Engineered with the most advanced available technologies, it is completely manufactured in Italy with high quality materials. Completely designed by electromagnetic simulation to achieve the maximun gain and optimize the radiation pattern and bandwidth. The new design of the radiant element works like a central feeded 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 an RF choke for optimum decoupling from mast and feeding line. Made of Fiberglass telescopic tubes, it is DC Grounded for the best protection from static discharges.

TECHNICAL DATA:
Type: 0.625 wave centernfeeded vertical dipole, *FREQ. RANGE: 25.5-30MHz 400CB channel & 10 m Ham Band, *IMPEDENCE: 50 oHM, *Radiation: Omnidirectional, *Polarization: Linear Vertical, *Max. Gain on the horizon: 1-2dB higher than conventional 5/8 wave, *Max Power: 500W constant, 1,000 Short Time, Lightening Protection: All metal parts are DC grounded. The inner conductor shows DC a short.

Antenna is approximately 24 Feet Tall and will handle 500 Watts

Out of all of the verticals that I've used, this one is the best. 15 feet off the ground and I can work most dx barefoot from Kentucky, and works great for local as well. I put electrical tape on all joints to help with stability.

I have never thought much of fiberglass antennas because they Bleed and too much RF.. but this Sirio Gain-Master vertical does a very good job on both tx/rx! I sill like aluminum antennas better.. but the Gain-Master does a far better job that other fiberglass antennas out on the market today. You Need To Try One For Yourself!

I own the 5/8 wave.. it is the best at wide bandwidth and RF Gain from 10-12 meter range nothing matches this.. nothing

I couldn't believe my SWR were FLAT on all frequencies. I was force to ask 4 of my friends to bring their radios to my home just to test and be sure. Incredible! They all purchased the Sirio GainMaster Antenna!!!

the gainmaster is the best ground plane type antenna i have ever owned..do yourself a favor and chop those antrons down an put one of these up..you wont be sorry..talking for 47 years
