• 50MHz J-Pole Antenna  ^pop - Need a general purpose antenna on the magic band? The J-Pole is an easy-to-build and inexpensive device that provides an omni-directional vertically polarised antenna without the need for a ground plane. In technical terms, it is an end fed vertical 1/2 wave which is fed via a 1/4 wave matching stub.

• 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

• Some plain facts about multiband vertical antennas - There is considerable confusion as to what exactly a multiband vertical antenna is. The confusion concerns the method of feed, how much mismatch one can expect, how many radials are required, how the particular antenna is built for multiband use, plus some other points.
