One thing that I have wanted to get for my vintage Futaba RipMax 4 transmitter, but couldn't find, was a ribbon antenna (clip) ....later to be found to be called a 'frequency penant or pennant'.
I searched online for images & also ones to buy, but the pictures were never really clear for the top of the antenna and also I didn't find any that, for what I wanted, cheaply enough. I then found an instruction manual for an ACOMS ATB-227 (Mk2) transmitter. It had a nice drawn sectioned view of the clip. So I thought I'd give it a go at drawing & 3D printing one.
I first drew the clip part for the antenna. After a few test prints I was happy with the grip. Next up was to draw the rest of it up. I assumed that the ribbon itself would be no more than 1" in width, so this plus the dimensions I'd collected off my actual Futaba's aerial, I was able to produce something to a scale.
I then found a picture (I think) eventually of the ribbon clip used by Futaba. It's looks basically like a coat hanger design lol......after all the designing for the above version lol.
So thought I might as well share incase anyone wants.
The printer I have access to, only prints at 0.2 & 0.3
I choose 0.2 for a test print.
