I get it, Tom had a problem and developed a solution for the problem. Due to popular demand, took it to market. No shade on Tom. I just figured with all of the Chinese companies in this market that tend to borrow from each other a lot, that some company would have added one of these onto a HF PCB by now.
I think the crux of the problem is the antenna design on the RDV4 seems to be a bit of a step backwards on the easy of use side of things compared to the RDV2. Namely because I leave the stock antennas on most of the time, and only put on the proxLF when I need to write to my implant. Having some sort of socket vs having 3 screws would make it easier to hot swap.
I wonder if I could just alligator clip the proxLF onto the screws…
