Thanks to "rcobo 101" for this simple, effective, multiband HF vertical antenna. Basically, the antenna is a vertical helix wrapped with 1/2 wavelength of wire for the lowest band of operation.  The winding serves as a 1/4 wavelength vertical and can be used with a suitable ground radio/counterpoise system and antenna "tuner" for the HF band of choice.  Although multiband operation is certainly possible with an antenna "tuner", this particular design works best on the band of your choice.  In this video, "rcobo 101" used 35 feet/10.670 meters of speaker wire wrapped as a helix on a 20 foot/6.097 meters telescoping fishing pole.  As such, this antenna is ideal for the 20 meter band.  According to "rcobo 101", his antenna "tuner" allows satisfactory operation on all amateur radio bands fr

Camping and Amateur Radio make an excellent combination.  Enjoy the beauty and solitude of the great outdoors while contacting the world with your portable "Go-Kit." Here's a nicely done video from K0PIR made during a camping trip to the Black Fox campground in the Black Hills of South Dakota...great scenery complimented by a fast flowing stream and pleasant surroundings. K0PIR's simple operating system is more than enough to get you plenty of contacts.  A simple antenna (with ground system if you're using a vertical antenna), a small antenna "tuner", a multiband HF transceiver, and a solar-powered battery should give you hours of fun and relaxation without all of the noise, traffic, and confusion of an urban setting.

An exceptionally well-made tutorial on how to build a simple delta loop antenna for the 6 meter Amateur Radio band.  Martin (M0ZMF) does an outstanding job of taking you through each step of the design and building process. This simple delta loop has excellent and proven performance.

W2LI Magnetic Loop Antenna. Post #1211.

W2LI Magnetic Loop Antenna (http://www.eham.net/reviews/detail/13332#148452). http://www.w2li.org/magloop). Author:  W2LI. Accessed on 05 August 2017, 21:05 hrs, UTC. Please click links or insert title URL into your browser search box to read the full article. Comment: Over the past few months, I've republished several videos and articles about magnetic loop antennas from the worldwide Amateur Radio community. Whether they be commercially made or homebrewed by radio amateurs, magnetic loops have allowed those with restrictive housing arrangements (HOAs and CC&Rs) to enjoy both HF and VHF/UHF radio operations again.  Magnetic Loop Antennas are easy to set up and break down, making them ideal for portable, emergency, and home use. While I enjoy making my own HF antennas, I can see the need for a sturdy, easy to assemble antenna for those of us lacking the resources for antenna parts or have little skill in designing and building antennas.  This is where products, suc

Bicycle Rim Magnetic Loop Ham Radio Antenna - Homebrew de KK6FUT. Post #1210.

This antenna project is one of the things that makes Amateur Radio so fun and fascinating--turning junk into something useful. In this case, KK6FUT has converted an old bicycle wheel/rim into a homebrewed magnetic loop antenna for the 15 meter and 20 meter ham bands.  The loop is made from a discarded bicycle wheel/rim after the spokes have been removed. KK6FUT made slits with a hacksaw and used an old AM/FM variable capacitor for tuning. While this loop is primarily for receiving, it can be used to transmit with a 4 to 5 watt signal. SWR measurements are quite good--1.0:1 on 15 meters and 1.4:1 on 20 meters.
