A 50mm former with provision for an SO-239 connector and holes pre-drilled with enough spacing for 24 revolutions of coax to form the choke.

This is designed for use on the 10m band HF frequencies.

46mm ID which provides enough room to slide over the antenna mast (I use a Haveford fibreglass 10m telescopic pole - I suspect others use similar diameters) with the ends of the coax running inside the former.

I mainly made this as I have the one fibreglass pole, but often like to switch which antenna is on it. This saves me having to have separate feed lines each time, and reduces the space taken up by the individual antenna in storage. 

The antenna design can be seen here on HamRadio DX's youtube channel (not me)

Printed in PETG, infill isn't really a factor, and I opted for 3 walls. Supports necessary for the square section only if printed upright.

Print 1 of each file. The coax cap goes on top. This is initially left open for ease of initial connection of the SO239 - though in hindsight, didn't end up needing it.

SO239 and top cap are attached with 3mm self tapping screws. M3x10 (8 of) will be fine.

This is not designed to be waterproof.
