Amateur Radio NFed Antenna

This is a case and setup for a simple End Fed antenna. I like these because the end of a long wire attaches to the pole and the other end has the antenna box which connects to the antenna cable. So you don't need a lengthy and weighty antenna cable going up the pole. It can be short and near the radio.

I'm not going to go into how to build the NFed itself. Basically you just need a toroid, a capacitor and a little magnetic wire. Here is a couple of links on how to put that together:

This but has a Bana jack on the top where the antenna wire plugs into. The wire is just over 63 feet in length. On the bottom it has a jack for the antenna wire. I include models here for both SMA and BHC connectors. It could also easily be modified for SO239. The Top wing-nut screw is for tension relief on the 63 foot antenna wire. The bottom wing-nut screw is also for tension relief and is connected to ground so it can be used as a counter-poise.

Here are all the components (all available on Amazon):

4 - M3 x 8mm wood screws
2 - 1/4-20 x 3/4" screws
2 - 1/4-20 Flange Nuts
2 - 1/4-20 Wing Nuts
1 - SMA Female Panel Mount Connector
1 - BNV Female Panel Mount Connector
1 - 4mm Banana Female Socket Jack
1 - 4mm Banana Male Plug
64' Wire for Antenna

To build the Antenna coil:

1 - FT-140-43 Ferrite Toroid Core
1 - 100pf 3kv capacitor
3' of 18 awg copper magnetic wire

I am also including STL files for the insulators is use at the end of my antenna wire and the STL files for some little wrenches I use to make assembly a little easier.

Everything is printed in PETG with 15% infill and no supports.

I design everything in OpenSCAD which is free to download and use. All the source files are included here.
