Amateur radio call sign W0EGR. We definitely learned the importance of bringing a backup antenna when doing portable amateur radio work for Parks on The Air. We cabin camped at Platte River State Park K-2621 in Nebraska. I brought the radio along and was able to activate the park on two separate days. The antenna we ended up using was an MFJ end fed half wave antenna. We ran the iCom IC-7300 at 100 watts SSB with a Bioenno 20 Ah battery for power.
