E-Field antenna
PCB
The circuit board is easy to assemble and should then look like this:
Simple Case
First, I created a simple housing with my 3D printer. It consists of a base part in which the circuit board is secured with screws.
The cover was a simple flat lid, but it did not offer any mounting options, for example, on a fiberglass mast.
Case with mast mount
To match the lower part of the housing, I designed an upper part with two eyelets on the top. A fiberglass pole can be inserted through these eyelets, allowing for easy attachment to the pole.
3D Printing issues
Printing in pure PETG
When printing this top part, it proved difficult to remove the print support on the underside cleanly. Printed entirely in PETG, the result was not convincing.
Printing in PETG with PLA support
However, the BambuLab channel on Reddit provided a solution within a very short time.
If PETG (gray) and PLA (white) are mixed in the support, the support can be cleanly removed from the underside.
