[Hi-zreceivingarraydiscussions] Filter needed for sure

[contact]

Hi Andrew,

The HPF would be the best practical solution.  What does your grounding 
look like? As I remember you are in rolling hills and the ground looked 
fairly good. If the soil is average or better and ground rod of 3 feet 
will work. Also keep the leads from the Hi-Z Amp to the base of the 
verticals and the amp to the ground rod about the same length and in the 
range of 8-10 inches long. Typically the base of the vertical should be 
as close to the ground level as possible, about 6 inches up.
