The Swiss Quad is an Antenna
based on the
HB9CV principle.

This experiment is a 6-band type
to compare with the famous HexBeam.

The antenna is constructed different from usual Swiss Quads.
The coaxial cable ist meant the same as / similar to the cable with the taps of the Hexbeam. The advantage that the coaxial cable on the Gamma-X is naturally grounded on one side and does not generate any sheath waves.

The longest pipes on the reflector side (red) are 5.0 and 3.6m. The Quad shall be 6m x 6m x 2,3m and shall have the lobe of a common 3-pole Quad (Reflector Dipole Director).

All electromagnetic used parts (SWR) are wires, no tubes.
The tubes are made of GFK material.

This antenna was never built on a mast, sorry. I only had a 1:10 model for the 2m-band and SWR and Smith diagram measurements with the AA-600.

Caution: these values are not 1:1 correct because the "wires only" construction takes some factor on the resonance frequency. The resonance frequency cannot modified with the Gamma alone! It is a matter of the size of the square. On common OneBand swissquads the resonance can be easily adjusted with the height but this makes troubles with this 6-band constuction with the tube angle.
