i know this is prob a dumb question reading the last part i agree
but i say how come ? they say all points are to be tied together at
enterance of house so what is the diff between any two proper grounds
connect points then?

From a safety viewpoint all ground points are equal.
For _RF_ however, one ground point _may_ be better then another,
depending on how the wiring goes through the house, and where the
ground wire is picking up QRM, hence Richard's suggestion to feed the
receiver from a wall outlet in another room.
