Description

  • 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 than the competitors.
  • The new design of the radiant element works like a centrally fed 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 the mast and feeding line.
  • Made of telescopic fiberglass tubes, it is DC-grounded for the best protection from static discharges.
  • All screws are stainless steel made, clamps are made of stainless steel AISI316, the bracket aluminum tube is made of alloy AW6060 AlMgSi anodized gray.
  • All metal components are made in SIRIO factories with the latest CNC lathes using CW614N brass and adequately protected by galvanic treatment.
  • The central pin of the UHF-female connector is 18 Kt gold to improve electrical contact and to prevent oxidation; the insulator is made of PTFE.
  • The low loss coaxial cable with red jacket used for the construction of the coil is built on SIRIO specifications by a leading Italian company and is wound around support made with the best material available for outdoor applications, the ASA.
