The first 11 Digital Tv stations channel are only 1.7 miles away. And are showing Very Strong signal strength , the first 5 Digital Tv stations are high lighted with RED , as being over the top strong signal strength.
Above the roof in such a manner that reception is not blocked by the roof and building in all directions , install a Winegard HD7000R antenna aimed at about 108 degree magnetic compass direction.
The HD7000R antenna is a small directional all channel antenna , the HD7000R antenna receives the best at the front and front angles of the antenna , and being a small antenna , it is not all that directional and will also receive good at , back angles and back of the antenna. So that includes the Digital Tv stations in other directions other then the front of the antenna.
Here is how to aim antennas ,

A preamplifier is not required. A preamplifier will be overloaded by the Very Strong local Tv transmissions.
I Do Not recommend a distribution amplifier. The local Tv transmissions are Very Strong and will most likely Overload and distribution amplifier.
The Zinwell box is a good converter box , However the RCA DTA800B1 converter box is a good converter box and is simpler to operate.
Current research: , it looks like the Basic digital to analog converter boxes are going out of production.
Many people are dumping there Analog Tv's because the price of Digital flat screen Tv's is dropping lower and lower.

If were to recommend a distribution amplifier , -->I Am Not recommending a distribution amplifier<-- , it would be a Channel Master CM3418.
