If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=JWZZlpHJKT8. A nice, simple, inexpensive 160 Meter Inverted L Antenna from Bob Holowenko.  Bob used 1000 ft/304.87 meters of 14 AWG (7 strand) wire, some rope, a simple ground radial system, and a few things found in his ham shack to build this winter time antenna for "The Gentlemen's Band." According to Bob, he used 127 ft/38.71 meters of wire for the vertical section of the antenna, six, 127 ft/39.71 meters of wire for the ground radials, and "a pile of random wire, including a fence" to complete his antenna system.  This video may give you a few ideas for the upcoming ARRL Field Day.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=bLLL0oFbNaU. Here's another idea for the upcoming ARRL Field Day from Carl (2E0EZT).  In this video, Carl takes to the field with camping gear, portable ham equipment, two major antennas, and a firm determination to succeed.  Carl was able to make some interesting contacts with his Yaesu FT-817, an Icom 706 mk1, a wire dipole, and the MP1 "super antenna." It doesn't take much to assemble a simple, effective portable ham radio station.  But, most of all, try to have some fun while snagging those elusive contacts.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=xxbfeOF3V7M. Some radio amateurs get very creative when it comes to apartment antennas.  Check out this video from KP4MD as she shows the "antenna farm" of N2LRB, who lives in a small Manhattan, New York City apartment. Here are the antennas from left to right: N9TAX JPole, Wolf River Coil with 102 inch whip (for use on 20 and 40 meters), 5/8 wave 2 meter mag mount, and a 5/8 wave 2 meter MFJ antenna. A clever use of space in a crowded apartment.

How To Install Ham Antenna Ground Radials. Post #1517.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=nnN0NVGqtKQ. Those of us who use vertical antennas for our ham radio stations know the importance of having a good ground radial system.  Ground radials supply "the missing half" of our quarter wavelength vertical antennas and make those antennas more efficient. Installing ground radials can be quite a task, especially if you want more than the bare minimum ground radial system.  In this video, Rich Rodgers uses an electric edger to dig  fairly straight groves to lay his radial wires.  You may want to keep the wires flat with plastic lawn staples available at many hardware stores.  This seems to be a good way to install ground radials.

Nicely done video by Eric of "Ham Radio Concepts."  Although every vehicle will be different, Eric shows us some of the common solutions to most mobile installation problems.  In this video, Eric concentrates on the installation of VHF/UHF transceivers and mobile antennas.  Please note the importance of grounding straps, proper fusing of power leads to the vehicle battery, and proper antenna placement.  Just take your time and do the installation correctly  Also be aware that some magnetic mount antennas may not work on car bodies made of aluminum and fiberglass.

If you can't see the video, please enter this title URL into your browser search box: https://www.youtube.com/watch?v=E4kBDWILTNE. While many U.S. and Canadian radio amateurs are preparing for the ARRL Field Day on 23-24 June 2018, our friends in Australia got an early start with the John Moyle QRP portable Field Day event earlier this year. In this video, Peter Parker (VK3YE) takes his Yaesu-817 QRP HF/VHF transceiver to a nearby beach, assembles a simple end-fed wire, adjusts his ATU (antenna tuning unit), and proceeds to collect some interesting contacts on the 80, 40, and 20 meter Amateur Radio bands.  The set up is ultra simple and entirely portable.  Peter located his antenna near the water's edge and got some excellent propagation for his low-powered signal.  For the latest Amateur/Ham Radio news and information, please visit these websites: http://www.HawaiiARRL.info. http://www.arrl.org. http://www.arrl.org/arrl-audio-news (a weekly podcast which is upda

Here's another expertly done video tutorial from Ray of the UK-based "Radio Workshop."  In this video, Ray show us how to build a simple, inexpensive L-match ATU (Antenna Tuning Unit) for the HF shortwave and Amateur Radio bands.  The ATU can be used with end fed "aerials", including inverted L antennas.  A definite must have accessory for radio amateurs using random length or inverted L antennas.  Don't forget to connect your antenna system to a good radial or counterpoise system.
