Radiowavz Sentinel Expedition

“Hope (KM4IPF) talks about the Radiowavz Sentinel Expedition Hex Beam that she and her siblings have been using. They have come up with a few time saving modifications. Later in the video, she is joined by Faith Hannah (AE4FH) and they put the antenna together in a fast timelapse video.

The kids have used this antenna several times in the field and it works amazingly well. It is incredibly directional and they have made hundreds of contacts with it during times of poor propagation. They have a 22 foot tall military surplus tower that can be set up with relative ease and this antenna works well on top of it.”
