Radiopopper production update
So here they are – a first glimpse of the P1 production units. Pictured are the v1.0 preproduction prototypes. These are functional units from the first short run batch. They were manufactured with micro sized internal antennas. These micro antennas, though highly and specially tuned for this application, failed to provide the even signal pattern they were looking for. The pictured units have been refitted with connectors for external antennas. The unit pictured displays the antenna to be used on final production units.
Both units sit on half of the enclosure to be used for production units. The finished dimensions 2.6 inches long by 2 inches wide, by 0.75 inches thick. The antenna length is approximately 4.5 inches. This enclosure is very slightly larger than the one they originally designed to. The original enclosure didn’t allow enough room for the antenna mount. A major bonus with the move to this new sized enclosure is they now have room for a standard AA battery. That’s right! They went from watch batteries, to AAA batteries, and now, finally – the battery you already own a bag full of – a standard AA. That’s progress!
