[Hi-zreceivingarraydiscussions] Filter needed for sure

[Andrew Cowan]

Hello All,


After installing my Hi-Z 3 and finally getting round to trying it I am 
getting hammered with strong am signals from 1107, 1052, 810 khz signals 
mixed on 160 and 80mtrs.
So going to buy the high pass filter not that I need it to go as high as 
60mhz up to 7.4mhz would be enough.
One question would be how do you know that the ground rod at the base of 
the verticals is sufficient for the system, I am getting good results on 
40m comparing it to my 4 square,
on 160/80 not been much about as yet to try.
