If you want all the benefits of a cubical quad,

If you want a small boom length and…

If you want the best on that boom length …

The 2 elements SUPER QUAD made by HPSD is the one you want.

 

This is a SUPER QUAD developed especially for those with limited space.  The antenna is “only” about 4 meters wide, has a height below 2 meters and a boom with only 90 cm.

But be not mistaking…still with very impressive figures !

This antenna is already capable of producing 7dBI and a front to back in the 30 dB region. Figures which have never been heard of on such a small boom length.

This, together with all benefits:

  • 50 ohms direct impedance
  • NO matching losses
  • closed loop configuration
  • less p-static
  • almost unlimited power handling capability.

Above the freespace azimuth plot.

 

With the antenna at 18 meters high, above average ground the total gain is 12,63 dBI under a 8 degree angle

Above the “freespace” elevation pattern.

A real life SWR measurent. A “peak” return loss beyond 30 dB !
