It's just a half-rhombic, but must suffer seriously from the poor grounding
that the ground rods provide. That will both reduce the front-to-back ratio
and make the input impedance vary (much) more with frequency.

According to US Army Signal Corps FM 24-18 chapter 3 section 7, poor
grounds can be helped with a dose of the following to increase
conductivity (in order of conductivity)

Sodium Chloride
Calcium Chloride
Copper Sulfate
Magnesium Sulfate
Postassium Nitrate

Course they also say dont let it get into the drinking water grin
