Often the most difficult and somewhat dangerous tasks of erecting a HF vertical antenna is placing the mast correctly, securing the guy lines, and maintaining stability of the mast until you're ready to test your new antenna. In this video by "ColdestMoon", we see an efficient, quick, and safe method of erecting a vertical antenna mast using a telescoping fiberglass pole, a few lawn anchors, and three strategically placed guy lines.  Don't be afraid to ask for help if your project needs an extra hand.

Good Ground on Small Lot. Post #1350.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=5RCvUpB7woU&t=50s. One of the major problems with vertical HF antennas is the establishment of a good ground radial or counterpoise system.  According to conventional wisdom, the ground radial system supplies "the missing half" of a quarter wave vertical antenna. In this video, Stan Gibilisco (W1GV) provides a working substitute for ground radials in a small urban lot.  The key is laying down as many 10-ft/3.048 meters ground radials you can and using the tallest vertical support (i.e. mast) available. While this solution is not as efficient as a full ground radial system using 1/4 wavelength wire, it will make your HF vertical antenna perform better than no radials at all.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=0eqrmAMYV20. 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.

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.
