- A two dollar helical hf portable antenna
- Here is an easily transportable vertical antenna for 20 meters collapsible to 4 feet that costs about $2.00 to make.
This was created as a fun project to demonstrate how to enjoy operating HF in the field with a home-made portable antenna without spending a ton of money.
Bev AH6NF (YL) made this antenna, tuned and ready to operate in less than one hour
