HF, 6m & 4m Antennas

The GPA-80 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.

The GPA-80F 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. It is the fibreglass version of the Moonraker GPA-80.

 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.

The upgrade kit enhances the 40m and 80m bands with its low angle of radiation, in some circumstances and installations it can mean the difference between white noise.

1.Please mount the bracket for the Plus Kit at the bottom of as per the photo.

2.Now attach the HF mobiles to the bracket. The HF mobiles can be angled horizontal or at a more vertical angle if space is an issue. Please ensure that the angle mounts are tightened up with the Allen key provided.

3.The 40 & 80 meter mobiles can be tuned in separately by moving the stainless steel whip up & down until SWR is achieved.

Probably the most popular wire antenna available, it has been used for many years.

For best performance it must be used with an ATU, especially if used on a modern solid state radio.

The full size version covers 80m to 10m, the 1/2 size covers 40m to 10m. The resonant bands are 20m and 10m respectively.

Same as the above antenna but made with new flexible "polyweave" cable, a woven copper wire with plastic covering.

For best performance it must be used with an ATU, especially if used on a modern solid state radio.

The full size version covers 80m to 10m, the 1/2 size covers 40m to 10m. The resonant bands are 20m and 10m respectively.

A 5/8 wave vertical base antenna for the 6m band, tunable 50-60mHz.

An aluminium mono-band base station antenna for use on 4m band. 

•  Base station antenna, Mono-band
•  Omnidirectional
•  Tunable 68-73MHz by tuning chart 
•  Protection from static discharges DC-Ground
•  Made of aluminium alloy 6063 T-832

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.
