My favorite amateur radio antenna is the easily-made and efficient delta loop antenna. In this video from Hiram Vazquez (WV2H), we learn the basic theory, construction, and performance parameters of this versatile HF antenna. Delta Loops display modest gain, have low noise, take up little room, and are inexpensive to build.  At my QTH, I have a delta loop similar to Hiram's.  The antenna's total length is 142-feet/43.29 meters and is attached to the top of a 33-ft/10.06 meters telescoping fiberglass pole.  The bottom portion of the delta loop is supported by two 10-ft/10.06 meters bamboo poles. The antenna is fed by a length of 450 ohm ladder line running into a 4:1 current balun. A short length of RG-8X coaxial cable connects the balun to my trusty Drake MN-4 antenna transmatch.  A small piece of RG-8X coax connects the &quo

Sometimes all you need to disguise your antenna is a clever application of your home's natural ground cover and geography.  In this video from AI4W, we see how a simple vertical antenna supported by a Jackite.com fiberglass mast can be hidden from neighbors and used even in daylight.  I'm reminded of an old saying: "Out of sight, out of mind." You may find AI4W's idea suitable for your HOA/CC&R-controlled home or apartment.

If you're having trouble viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v=vwkxSXmhAZY. Anderson Power Pole Connectors have many uses in your ham shack from connecting power supplies to transceivers to hooking up test equipment. In this well-produced video from Randy Hall (K7AGE), we learn a different method of attaching powerpole connectors to the various wires running through our radio rooms.  Until I saw this intriguing video, I always used the crimping method to attach the power pole connectors.  In this presentation, Randy uses a soldering iron/tool to attach the connector. Both methods will work and the choice is up to you.  Randy's news Logitech 920 camera does an excellent job of presenting this tutorial.

If you're having trouble viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v=uf32ecwFjjQ. My series on Windom Antennas continues with a practical demonstration of this classic amateur radio antenna from the 1920s.  In this video from Peter Echer, we see a 160 meter Windom Antenna in action. Peter claims this large antenna and his 50 watt transmitter output often outperform small beams, dipoles, and verticals. Peter does a good job of showing how to build this off-center dipole.  If you lack the space Peter has, try a Windom Antenna designed for 40 through 10 meters.
