These are antennas that we have built that any club member can build and take home.
We have parts in stock for some of these. If you'd like to build one at the next project meeting, tell us ahead of time so we can make sure we have materials!

VHF UHF[edit | edit source]
- J-pole antenna
- omnidirectional tuned antenna; The J-pole can be built for any band really but is easiest for VHF and shorter wavelengths. It's a great first antenna for a new tech, as it can extend the range of your HT or mesh node.
- tape measure yagi
- directional tuned antenna, perfect for fox hunting
- Moxon antenna
- directional tuned antenna; practical for 70cm and longer wavelengths; basically a stable folded yagi
- WiFi antenna
HF[edit | edit source]
These are much bigger!
- EFHW antenna
- This is an all band HF antenna that needs a tuner and needs to be hung in a tree.
- Free standing portable HF vertical
- This uses a commercial telescoping whip and adds parts to extend the range to longer wavelenghts while keeping it portable without needing trees.
- HF moxon
- future plans for 10m and longer wavelength moxons!
- Windom
- This is a tune off center fed dipole designed to be hung between 25-35 ft up. Typically good for 20-40-80m but can add 10m with a cheat (carolina variation) and can be tuned to other bands with a tuner.
