Print these 2 parts using at least 50% infill and use either High Temp PLA+ or if you are going to actually use it as a permanent antenna, maybe PETG might be a better filament choice though FilaCube's HT-PLA+ will withstand the elements very well...

I have recently purchased the Sota Beams 7 Meter mast and the drive on stand.  When you put the mast into the drive on stand there was too much play for my liking so I designed a mast support. The mast support is printed in two halves. (Printed...

<p>A simple clip to pass antenna wire through and to be held by a carbon 6 pole or pretty much any fishing pole with a decent enough top section (i.e. ...not the very fine squid pole types).</p><p>The simple version should be adequate for most...

I wanted a wire winder and unun case for my very small, very efficient transformer. With smaller cores, you need a cover over the core. Since it's wound with 22 gauge wire, it can't just be left in the open. The cover snaps in place without hardware....

I added a hole so you can view the LED and labeled the 3.5mm jacks IN for key or paddle and OUT for headphones/speaker.

Winder and case for endfed half wave antenna for portable radio operation like SOTA or POTA. QRP version (about max. 50 W SSB, 25 W CW) with FT-114-43 torroid and enough space for thin 20 m wire (40/20/15/10 m band version). Wire needs to be tuned...

Eclipse NVIS Antenna 40m 20m (15m) 10m this antenna is meant to be an all in one package for emergency NVIS communication. can also be used for POTA for those local QSO in your skip zone. the goal is quick deployment, lightweight and small size. ...this...

This calls for a QRP End Feed Half Wave Antenna Transformer built around a T50-43 Toroid. To build one, you'll need a T50-43 Toroid, Banana Plug, 100-110pf Silva Mica Capacitor rated at 1kv, Enamelled Copper Wire for the windings, BNC Panel Mount...
