I am currently owning 2 tamtechs; GB-01T and GB-03 chassis. 1/16scale model.

I understand that there is inbuilt antenna fixtured (holes where you plug the antenna tube directly in). But the antenna plug that i see online always has screws together as a package. Hence i deduce that i required some sort of clamping actions that anchors itself onto the chassis.

For the time being i do not see any chance of mounting after market antenna holder.
