Summary

The same but smaller and stiffer with 2 30mm long nut to hold the telescopic antennas, faster to deploy, no more toroid nor guanela just an "ugly balun" to cut the antenna. only for 28Mhz up to 150Mhz. screw the telescopic antennas and it works perfect in 10M. this is a balcony SOTA POTA antenna it is not for permanent use because of the telescopic part that is really weak, if tou replace the telescopic parts with aluminium it will work fine a long time. For the plug and the mayor parts use epoxy and it will last a lot of time. The one version with 5m telescopic antennas is removed beacuse here in thinguiverse is a 100 times better solution therefore im not going to discover the wheel. The idea of the holes are for screws for gluing both front and back part, if you want you can leave them but with epoxy it will last a lifetime and metal parts near the antenna is not a good idea.
The plug cover was a fantastic solution that is here in thinguverse and it was remixed to fit my needs an to hold the female BNC conector.

for the big 5.6m telescopic users, go for this here in THINGUIVERSE.... https://www.thingiverse.com/thing:7014746/files

and the plug housing was a remix from this one https://www.thingiverse.com/thing:4872205
