How fast can you erect an all-band HF vertical antenna?  In this video, we see how a little pre-planning can reduce build and erection time to less than half an hour.  According to the video's author, this antenna "covers all bands on HF without a tuner with pure quarter wave elements (5/8th on 15 meters)."  Total time from beginning to actual on-air operation was about 25 minutes.  Interesting video.

An exceptionally clear and simple demonstration on how to operate the popular AM-2 Z-Match Antenna Tuner kit by Emtech.  Alan (W2AEW) takes us step-by-step through the operating parameters of this small, highly flexible antenna tuner. Alan says he's been using this Emtech kit for almost a decade without major problems.  The Emtech antenna tuner "does a nice job indicating when a match is achieved, especially when a SWR meter isn't available."

Installing PL259 coax connectors on your antenna feedline is an often a necessary and tedious task, especially when you use thicker coax such as RG-8 and RG-213.  In this video from Jim (W6 LG), we learn an easy way to install those pesky PL259 connectors in 3 minutes or less.  If you have the proper tools, the job goes much faster and far neater than just stripping cable, rolling back the braid, and dropping hot solder on the connection.  Jim's method is simple, effective, and easy to learn.  For the latest Amateur Radio news and information, please visit these websites: http://www.HawaiiARRL.info. https://oahuarrlnews.wordpress.com. https://bigislandarrlnews.com. http://www.arrl.org. http://www.arrl.org/arrl-audio-news (a weekly podcast which is updated each F

Tuning the 40/80 Meter Inverted V Dipole Antenna. Post #1345.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=IKuLDnwuy8M. A coiled loaded 40/80 meter Inverted V Antenna is ideal for a small urban backyard.  If you use a PVC pipe mast or a telescoping fiberglass support, you can raise and lower this antenna quickly. Other than designing, making, and erecting the inverted v, the only other issue with this simple, easily made antenna is tuning the antenna--something that must be done to reduce SWR and RFI in your shack. In this helpful video from Dave Tadlock (KG0ZZ), we learn how to tune this coil-loaded inverted v in a few easy steps.  Why not make an inverted v antenna as a back up for your current antenna?  Inverted Vs also make excellent portable and emergency antennas.

If you're looking for an experimental antenna you can use in deed-restricted properties (HOAs/CC&Rs) or for portable and emergency operations, the magnetic loop antennas described by Kevin Loughin (KB9RLW) may be what you need. Kevin does an excellent job of explaining the theory, design, construction, and  use of these small antennas.  He also discusses the limitations and safety concerns related to magnetic loop antennas.
