This video offers a good, clear, and simple way to design and build a 9:1 UnUn for "Long Wire Antennas."  Tinker John (W5CYF) says this inexpensive, one-evening project uses locally available materials and will prove useful for both portable and home operations.  Why not make one for your emergency "Go-Kit?"

If you want a cheap, easy to make, and totally portable antenna for your next operation in the great outdoors, then this excellent video from WI9LL may be what you're looking for. According to WI9LL, the antenna was built to meet the need "for low wattage QRP use"...and designed to be "compact and inexpensive." The antenna uses a 9:1 UnUn wrapped on a T-10602 toroid, "using minimal hardware to be lightweight."  A very nice, compact antenna.  Why not make one for your emergency "Go-Kit"?

If you live in deed-restricted housing (HOA/CC&Rs), this video from KG5OCW is a must see.  This well-produced and easily understandable presentation should give you several ideas for mounting an outdoor HF antenna while avoiding the attention of nosey neighbors.  The important thing to remember is "out of sight, out of mind."  When all else fails, use an indoor antenna mounted in your attic or a simple HF magnetic loop antenna that can be set up  and taken down quickly in your backyard.  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 updated each Friday afternoon). https://oahuarrlnews.wordpress.com. https://hamradiohawaii.wordpress.com. https://bigislandarrlnews.com....

Fascinating video from Kevin (KB9RLW).  The short answer is yes, depending on ground conductivity and the local noise environment.  Kevin shows us that a "ground antenna" does work if you're willing to accept less than stellar performance.  There have been some SOTA (Summits on the air) events where ham antennas have been located at high altitudes without the benefit of trees or other supports.  Contacts were made despite the limitations of height above ground.  It's also worth mentioning the "Grasswire Antenna" from K3MT which seems to work fairly well.  Check the blog sidebars for the K3MT "Grasswire Antenna" page, which gives the specifics for this antenna. While on-the-ground transmitting antennas may not perform well, receiving antennas mounted a short height above ground seem to produce excellent res...

It's amazing what you can make with just a few feet of wire, a few connectors, ceiling hooks, tape, and some creativity. In this video, we see a few examples of HF wire antennas which can be made from locally available materials.  This video does a good job of showing the construction details of an inverted Vee "Slinky" antenna, a modified half square antenna for 20 meters, and an indoor two-turn HF loop. Getting on the air may be as close as your garage, storage room, and the proverbial "junk box" kept by most radio amateurs.  Don't be afraid to experiment with homebrew antenna designs.  That's part of the fund of being a ham radio operator.

In this video, Callum (M0MCX) shows us a very simple way of double checking how much to trim your vertical and dipole elements.  The calculator is a great tool with the spreadsheet easy to understand.  All units are in the metric system, so those of us still using the old foot and inch measurements will have to make a few simple adjustments.

Ham Nation is one of my favorite video podcasts.  Each issue covers several fascinating aspects of Amateur/Ham Radio. In this video,we get an extensive discussion about the theory, construction, and use of Loop Antennas.  The Loop Antenna portion begins at 5:59 and ends at 13:48.  Other parts of the video include a Christmas in Finland, installing powerpole connectors, and Winter Field Day.
