Cut the active element wire (radiator) to the specified wire length (see Column: Wire length“. Attach the banana plug to one end of the wire. Make a fold back at the other end of the wire (length see column „Foldback Lenght“ and attach the 3d printed „Loop Maker“. Cutting chart active elements (radiators): Band Element … Weiterlesen

There are two options for threading the radiator elements. Either via the threading gap. This is a good option if the radiator elements are thickened with shrink tubing at this point. In this case, the radiator element can simply be threaded through the gap. The second option is to close the gap with a cable … Weiterlesen

The VMA3D is based on the M0MCX concept for a vertical multi-band antenna with radiator for the corresponding amateur radio bands. Once tuned, the antenna does not require an antenna tuner and thus enables a quick band change. What makes the VMA3D stand out is the integrated clamping device with which the plates and clamping … Weiterlesen

The individual elements of the GFA mast are secured with 3D printed clamping rings. The clamping rings always sit on the lower transition. The advantage of using the clamping rings is that the GFA elements only need to be lightly clamped together, which simplifies dismantling.

The 3D print for holding the radiation elements is printed with PETG filament and has the same basic concept as the base plate. The only difference here is that angled 4 mm banana plugs are used instead of the straight 4 mm banana plugs. The radiant elements of the radiator plate are connected to the … Weiterlesen
