Why bundle portable field tools?
Parks, summits, and field day mean no cell signal and tight power budgets. This bundle groups POTA/SOTA calling frequencies, antenna sizing, grid squares, coax loss, lightning safety, and the field power hub so you can plan the whole activation offline.
Log contacts with the field QSO log and export CSV when you get home. For emcomm deployments, pair this kit with go/no-go and the HF emcomm bundle.
