Had a query: “Secondly for special targets like obleisk monuments and masonic lodges- are HHGs necessary rather than TBs? If yes how many.”
In my experience, a few TB’s is enough (2 or 3), although the last monument I gifted was only one TB. Need I say, overgifting is no crime, but don’t feel bad if you do not leave a HHG behind. My local freemason temple has only one or two TB’s, and the energy is pristine over there.
Mind you around monuments usually there are considerable amounts of antennas to be found.
