Know this about the antenna modification web sites.
Most avoid telling the complete truth.
The complete truth is that.
All antennas are a compromise antenna design.
Their is No magic antenna modification.
Improvement of one aspect of a antenna will mean a reduction of another aspect the antennas reception.
