Comment: Here's another great antenna idea for those who want a better signal on 20 meters but have only a restricted space to erect an antenna. Pleun Vermeulen (PA3HHO) has designed a simple, sturdy, and efficient 20 meter dipole made from aluminum tubing and materials available at your nearest hardware or home improvement outlet.  Pleun provides helpful drawings, antenna patterns, SWR readings, and general construction tips to help you make this simple, yet effective antenna.

Balcony Antenna for 7, 10, 14 MHz (http://www.dxzone.com/cgi-bin/dir/jump2.cgi?ID=31441). (http://www.cqham.ru). Accessed on 18 November 2016, 04:45 hrs, UTC . Author:  Valerei Prodenov (UR5WCA). Please click the title link or insert the title URL into your browser search box to read the full article. Comment: Here's another great idea for an antenna suitable for a crowded urban area or in places where HOAs and CC&Rs limit the type of ham radio antennas available. Valerei does an excellent job of describing his vertical helix antenna which covers the 7, 10, and 14 MHz amateur radio bands.  He includes a list of materials and some helpful construction hints. I still use a vertical helix for 80 meter operations.  I feed my vertical helix with 450 ohm ladder line which terminates in a 4:1 balun/manual "tuner" arrangement.  Over the past few months, I've managed to lay approximately 25 quarter wave ground radials to improve the low efficiency of the a

Review Summary for MFJ 2286 Big Stick Vertical Antenna (http://www.eham.net/reviews/detail/10436#144586). Accessed on 15 November 2016, 15:55 hrs, UTC . Source:  http://www.eham.net. Please click title link or enter title URL into your browser search box to read the full article. Comment : Those of you searching for a simple, effective, portable HF antenna may want to consider the MFJ 2286 Big Stick Vertical Antenna.  The antenna consists of a 17 ft./5.18 meters steel collapsible whip paired with an adjustable high-Q-air-wound coil.  The antenna covers a frequency range of 7.0 MHz to 55 MHz. As you can tell from the comments of actual users, the antenna ranges from very good to barely passing.  Most of the issues center around quality control problems--long an issue with MFJ.  Despite these shortcomings, the antenna does very well in real world situations.  Just be sure to protect the coil and coil tapping clips from the weather.  If you're willing to make some struct
