do not know which model is best
in the old days there were radios for vehicles
you mounted an outside antenna on it just like the regular car radio only bigger
for in the house they called those your base radio it just sat on a table or whatever
cant remember if they had an outside the house antenna or just a bigger one built inside
popular in the 1970's before cell phones
in the 80's or so the sunspot activity made them lose range compared to before
then the cell phone came along
were very handy on the farm
