Thanks to Dave Casler (KE0OG) for this interesting J Pole Antenna.  The original design comes from Jerry Bustin (KR7KZ), who made these antennas in the 1970s.

Here are a few comments from Dave: Here's an unusual Jpole antenna sent me by Jerry Bustin, KR7KZ. He first made these in the 1970s while stationed in Okinawa. Interesting feed arrangement.

  Here's another fascinating HF antenna for those living in deed-restricted apartments and homes.  Although the antenna from TN07 Engineering is a bit expensive, it could be what you need to stay on the air.

Here are some comments from the video: Another way to beat the HOA commandos when you want to operate ham radio. This antenna can be very hard to notice at all if you set it up in a stealthy way. 80-6 meters, SWR less than 2:1 across 80-6m, and handles 100 watts.

  Here's an interesting idea for portable operations--using an antenna below ground level.  In this video, "Outdoors On The Air" shows us how a nearby body of water can enhance HF signals. If you can see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=u2SKuQMzCu8 This is post 2822 in a continuing series of simple ham radio antennas. Here are a few observations from "Outdoors On The Air": We all know that deploying a ham radio antenna as high above ground as possible is the best choice, but would deploying an antenna below the surrounding terrain work at all? Join me as I put this idea to the test. N9SAB antenna store: https://www.ebay.com/str/n9sab ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).

Thanks to Bret of the "SurvivalComms" youtube channel for this simple, easily deployable HF antenna.  You may have most of the materials at your home station, thus reducing the cost of this project. As with most random length antennas, you'll need an antenna transmatch (i.e. "tuner") and a good counterpoise/ground system to get maximum efficiency from this antenna.

Here are some comments from Bret: Short video on a simple multiband HF antenna (w/tuner) you can put on the air with a few mulitpurpose items in less time than it takes to watch this video. ----- Thanks for joining us today.

If you need a "super multi-band antenna", then this "Lazy-Loop" from Tim (G5TM) and Rick (DJ0IP) may be for you.  The time spent in designing, building, and testing this loop antenna is well-worth the effort.

Here are a few comments from Tim (G5TM). Thanks again to Rick, DJ0IP for publishing details of this antenna which he says provides great gain at higher angles for 80 and 40 metres as well as very good gain 20 metres through 10 metres. Let’s use MMANA-gal modelling to see if this agrees. Check out Rick’s website here: https://www.dj0ip.de/my-favorite-ante...

Thanks to Callum McCormick (M0MCX) for this easy way to get height for your stealth wire antennas. The secret is to buy a few "aluminum scaffold poles" for antenna support. If you can't view the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=4KQEQJ5qeuw This is post 2815 in a continuing series of simple ham radio antennas. Here are some comments from Callum: Great tip for getting stealthy height for your wire antennas. Particularly useful for folks who don't have trees strategically placed. Aluminium Scaffold Tubes slip inside Sail Board / Wind Surf Masts. Then you can paint to suit. Cheap, economical and structurally sound. Background: My name is Callum, callsign M0MCX. The whole DX Commander brand was a bit of an "accident" since I already have 2 day-jobs (I own a couple of tech companies). Everything I make, I use myself. My products are the answer to *my* problems so I made stuff that worked for me. I ...

If you have limited space for HF antennas, then this tutorial from "TheSmokinApe" you tube channel is for you.
