80m - 6m

The X80 is an end fed aluminium vertical antenna, capable of allowing the user to work 80 meters through 6 meter bands using an ATU, also not requiring any counterpoise and can be fed using coax cable.

The antenna can be pole mounted at ground level or elevated depending on the user personnel requirements. It is rated at 300 watts pep and comes complete with all fixings and fixtures and full installation guide.
 
How it works: The antenna is fed using coax via an SO239 socket at the base of the unit a UNUN transformer is located in a weather sealed box at the bottom of the 6 meter telescoping aluminium element. The transformer reduces the high impedances generated to a more acceptable level making the antenna much more efficient and allowing proper and easy tuning via a manual and most automatic ATU’s. The antenna can be grounded if the user experiences excessive local static noise, but as the UNUN is DC grounded, grounding will not effect the tuning ratio’s.

      80m - 10m
      The HF-360 is an end fed vertical fibreglass antenna capable of allowing the user to work 80 meters through 10 meters using an ATU, also not requiring any counterpoise.
       
       The antenna can be pole mounted at ground level or elevated depending on users requirements. The antenna is rated at 300 watts side band. The antenna comes complete with fixings and full installation guide.
       
       The antenna has 4 sections, 3 high grade fibre glass sections and one stainless steel whip.
    • Type End fed vertical
    • Frequency TX / 3.5 - 29 MHz
    • RX / 1.8 - 55 MHz
    • Power handling 300 watts pep
    • Impedance 50 Ohms
    • Connector SO-239
    • Length 5.4 meters

      How it works:
      The antenna is fed using 50 Ohm coax via a SO-239 socket at the base of the unit. A 6:1 UNUN transformer is located in an IP65 weather sealed box at the bottom of the bracket section of the fibre glass elements. The antenna comes in four parts, three  fibreglass poles and one stainless steel tapered whip. The transformer reduces the impedance at the feed point to a more acceptable level making the antenna much more efficient and allowing proper and easy tuning via an external ATU and automatic ATU’s found in most modern radios.

      The antenna can be grounded if the user experiences excessive local static noise, but as the UNUN is DC grounded, grounding will not affect the tuning ratios.

      The Highlighted bands in the chart below will require a manual ATU, the others an internal ATU.

      5 band trapped vertical antenna

      A high quality HF base antenna made in the USA.

      Exclusive trap design makes Hustler traps ultra stable and dependable.

      Not only can you adjust the frequency by tubing length, the can actually tune the traps for up to 2MHz shift.

      Large diameter tubing gives full bandwidth on 10m to 40m.
      On 80m you get around 100kHz bandwidth.

      The absence of tapered tubing makes this antenna really rigid and the 8mm base tube wall adds to rigidity.

      Can be ground mounted or elevated.
      Radials need to be supplied by the user.

      Gain-Master Hi-Tech Fibreglass Base Station Antenna for CB & 10m Band.

      Gain-Master™ is a 5/8λ high tech fibreglass base station antenna for CB and 10m 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 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 mast and feeding line.
      Made of telescopic fibreglass tubes, it is DC-grounded for the best protection from static discharges.

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