Couldn't load pickup availability
The "Just OK" Mini Antenna is an ultra portable antenna for use on 20m (14Mhz band). It is a ridiculously small 20m antenna that packs up to about 6-7".
UPDATE Oct 24: This product is to pre-order. We are shipping in the order that orders are placed and have been shipping orders as they are built and tested. Orders placed now are estimated to ship mid to late November. We are very thankful for the demand and working very hard to minimize the delay for anyone.
We were vacationing in Florida in an airbnb with no place to deploy an antenna. That was when this ultra-portable "Just OK Mini" Antenna was born!
This antenna is a vertical antenna with a loaded base. It works by using an extendable whip that is just 7" when collapsed and extends to about 5' (1.2 meters). The loaded base allowing it to be used for the popular 20m band without a tuner, by resonating on 20m and matching to your radio. It has a built in ground connection so that you can use it with the many popular QRP radios that don't have easy ground connections. You can also mount it just about anywhere, as it also features a standard 1/4" tripod connector for connecting to any standard tripod or tons of mounting options from Amazon.
This is not a perfect efficient antenna. Actually, it is far from it. We call it the "Just OK Mini" because it is Just OK but gets the job done. It might be the only antenna you can deploy in some situations. This might be a compromised antenna, but it allowed Becky to make a contact from almost 5k miles away in the Netherlands and Mike to make contact with England.
This antenna was created by us, the HamRadioDuo, for the way that so many of us love to operate. It works with the popular affordable radios such as the QMX, QCX-mini, and G90, including the ones with no tuner and no easy ground connection. We love inexpensive gear and wanted something that would pair well on price also.
This is the tripod we use for our camera and have been using for the antenna. There are lots of options for standard 1/4" tripod mounts, including ground spikes, on Amazon.

Why You’ll Love It
-
Pocket‑Sized Portability
You can bring this with you anywhere and deploy without space requirements.. -
Tripod‑Ready
Screw it onto any standard tripod mount—small tabletop tripods, rugged camera tripods, or even a simple ground‑spike base. There are tons of options on Amazon (see link above). -
Built‑In Ground Connection
A dedicated ground lug makes it a breeze to attach the included 13 ft radial bundle. Perfect for radios without a chassis ground point (hello, QCX Mini!). No extra adapters needed. -
Tuner‑Free Operation
Factory‑tuned to the lower portion of the 20 m band, you can be on‑air instantly. Want to slide up the band? Just shorten the whip a hair—no external tuner required.
Why You Might Not Love It
-
Not very efficient
Like any of these types of antennas it is highly compromised. That means it will turn your QRP signal into extra-QRP. It may have a low SWR, which will make your radio happy, but that doesn't mean you are getting all the power out. -
No tuner needed, but you'll want to use an analyzer
You'll want to bring an analyzer with you for a quick check and final tune by adjusting the whip before each use. The frequency where the SWR dips can change significantly based on the environment – how far it is from the ground, if you are near metal, and even how close you are. Also, compared to a full sized, efficient antenna, the useful bandwidth is very narrow, so you'll want to make sure the dip is where you want it.
