The antenna you are using is a high gain UHF directional antenna. Can't say whether it is useful or not without the TV Fool Report.
Also include:
1) Where is your antenna located? Living room? Attic? Roof?
2) What direction is it aimed?
3) What is along the line-of-sight from the antenna in the direction of the towers (you can use the lines on the map to determine this)? Trees? Buildings?
4) List the channels you receive well and those that are spotty. Include Real Channel number and call letters.
5) List the channels do you want that you don't get?
