The results of this simple antenna are impressive, given the small size of the magnetic loop.  Proximity to the ocean is a definite plus for this antenna. Peter has produced a nice collection of video tutorials for your library.  Here are some of his remarks: "Pedestrian mobile on 28 MHz with FT817 & 40cm magnetic loop antenna. PS: Like these videos?

If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=lsGXJxNkfb8 Thanks to John Saunders for this quick video describing his home made 40 meter ground plane antenna.  According to John, you can assemble this portable antenna is only five minutes. The antenna is simple and can be stored in a small bag or pouch.  Most of the antenna materials can be bought locally or through online vendors. Here are some of  John's comments: "This video is about a simple portable 40m ground plane antenna that will go up in only five minutes flat!

The Flying Antenna. Post 2158.

If you can't see the video, please insert this title URL into your browser search box:   https://www.youtube.com/watch?v=-VWBUDJv2n0 Radio amateurs have used all kinds of objects to support their HF/VHF/UHF antennas--including in this case a helium filled balloon.  According to the video's producers, Glenn (N6GN) and John (K6PZB), results were excellent during the brief test with an approximate 40 dB signal improvement over previous antennas. Here are some of their comments: " helium balloon supported antenna tethered and fed by a surface wave transmission line provides more than 40 dB increase in signal strength of amateur radio communications. This is essentially the same presentation given by N6GN at ARRL Pacificon in October 2011. Related SWTL projects & theory in ARRL QEX May, July, November 2012.

Here are some observations and links from "North Carolina Prepper": "Playing with a magnetic loop antenna. you can make them really cheap with just wire. There are plenty of plans on the internet.

This excellent, easily understood video shows how to determine the proper feed line length so you can tune all amateur/ham radio HF bands.  You should use this feed line in conjunction with a balun and a wide-range antenna "tuner."

100 watt 7 MHz magnetic loop antenna for units and apartments

If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=Cv_RnLpZ9gw .  This is Post 2155 in a continuing series of simple ham radio antennas. Radio amateurs living in urban apartments or in deed-restricted housing often have a difficult time getting on the air because of limited antenna options. In this video, Australian ham Peter Parker (VK3YE) gets around the limited antenna space problem by building a fairly compact magnetic loop antenna for the 40 meter Amateur/Ham Radio band. Here are some of Peter's observations: "A description and demonstration of an ultra-simple but 100 watt capability 7 MHz magnetic transmitting loop for units and apartments. There are no hard to get parts or complex workshop skills required to build. Instead of the expensive vacuum variable capacitor, the loop is brought to resonance with a length of RG213 coax (approx 1.85 metres for a 3m circumference loop for 7 MHz).

A timber antenna mast. Post 2154.

If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=tWq4tgLH-yI While most antenna masts these day seem to be built from various metals, telescoping fiberglass poles, and PVC pipe, a few adventurous radio amateurs are returning to "classic" wooden masts that were common a century ago. In this post from Peter Parker (VK3YE), we see how simple a wooden antenna mast can be if you are careful in designing and building the structure. Here are some of Peter's observations: "Timber mast suitable for supporting lightweight wire antennas. The mast is 6 metres tall plus a 2 metre top extension. It tilts over for easy work on antennas. The antenna supports dipoles for 40, 20 and 10 metres, coming off the one feedpoint. 15 metre operation is provided by the 40m dipole. 80 metres is covered by adding loading coils to the 40 metre dipole. The antenna is similar to VK5AH's dipole except the
