A properly designed and built random wire antenna makes an excellent portable or emergency antenna.  In this video, Larry (WD0AKX) shows us how he set up a simple, backyard ham station using only the materials found in his shack.  All you need is a rig (in this case Elecraft KX-3), an antenna "tuner", a unun matching unit, a random length of wire, a power supply, and a simple ground radial or counterpoise system.  To choose a suitable random length of wire for the antenna, please visit this website:  http://udel.edu/~mm/ham/randomwire/.  Good luck with this simple, fun to use antenna.

10 Ultra Stealth Antenna Designs for HOAs. Post #1563. https://forums.qrz.com/index.php?threads/10-ultra-stealth-antenna-designs-for-hoas-260566/ Author:  KC8VWM.

Comment: Operating an amateur radio station from a deed-restricted property controlled by an HOA or some CC&Rs can be quite a challenge.  Before my xyl and I bought a home in the Puna District of Hawaii Island, we lived in apartments or rental homes that had strict requirements for any outside antennas. During those years, I was able to use a variety of loops, loaded verticals, and even mobile whips attached to my old Toyota Corolla sedan to get on the air.  Believe me, this was an adventure.  Over the years, I came across several stealth antenna ideas which have proven useful and even fun to use. In this article by KC8VWM, we discover 10 clever stealth antenna ideas that should get you on the air without neighbors

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=DWR5d7t0WAw. If you want to experiment with a simple antenna using locally available parts, you may want to build the often controversial "EH Antenna",which has drawn both praise and criticism from both radio amateurs and commercial broadcasters. In this video, OM0ET duplicates a design by wb5cxc for use on the 40 meter Amateur Radio band. Build one and see for yourself if the antenna claims are true or false.  You can find an online calculator for this antenna at this website:  http://www.wb5cxc.com/design_eh.html.

Building a ZS6BKW antenna from scratch. Post #1559.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=BfUbL_4VCww. The G5RV and its popular variant, the ZS6BKW, are popular multiband HF antennas for radio amateurs. In this video, members of the Stamford Amateur Radio Association W1EE,  show us how to build a ZS6BKW antenna capable of covering the 80 to 6 meter amateur radio bands.  Here are the guidelines offered by this construction team: "The ZS6BKW is the successor to the G5RV. It's a multi-band 80-6 meter wire dipole. ZS6BKW started with the G5RV and then conducted extensive computer modeling to increase the gain, flatten the SWR a bit, and smooth out the lobes. It's also about 10 feet shorter than an equivalent G5RV. The antenna must be fed with 39 feet of 450 ohm ladder line and also must have at least 70 feet of coax feeding the ladder line. The coax and ladder line together form a matching network that brings the SWR below 2:1 (

Here's another fascinating video from Peter Parker (VK3YE).  In this post, Peter shows us how to build a magnetic loop HF pedestrian mobile antenna for the 40 meter Amateur Radio band.  Peter compares copper and aluminum magnetic loops and shows how to adjust them for maximum performance. According to Peter, "Stations worked were between about 300 and 1500 km distant."
