YES! This is VERY important advice, trumps all else.
And I echo those who have advised to build one vertical radiator with an
excellent radial system, and the best RX antenna system that will fit on
your property. Most of the arrays others have suggested are not
practical on five acres, if for no other reason that a GREAT radial
system for each element is critical.

This is a great piece of advice!!! I would add: check those QRN levels at
various times and on different days.

... before you even make an offer on a piece of property, go there with a
mobile receiver and check to see what the ambient QRM level is. We have
already read in this group about this very subject from a ham that is
unable to use 160m due to the QRM from pot house grow lights some 3/4 miles
away. LED lighting is a well known source of QRM.
Certain types of TVs and even solar power inverters can cause horrendous
amounts of QRM which can render top band useless. It is interesting to
note that there are no FCC spurious emissions requirements for solar power
equipment.
