SFH 1×3 Enhanced is OK than SFH 1×1. The occupancy of SFH 1×3 Enh is OK than SFH 1×1. (there are back to back and face to face)
For rural site where no neighbor, it is better to propose non-hopping system rather than hopping system(BBH or SFH).
And for coverage impact, I think it should be no problem, the coverage will be same (same EIRP)
Correct me if I am wrong.
