Over the next few weeks, I'll be featuring some interesting antennas that you can use for the upcoming ARRL Field Day on 23-24 June 2018.  Although many of my fellow radio amateurs will join their club at public parks, schools, and emergency operations centers for this annual communications exercise and popular contest, some of us (including yours truly) will be operating a single station on battery or solar power in whatever space we can find. In such situations, our antennas must be versatile, sturdy, and easy to erect.  In this report from "VideosByDPF", we see an excellent "one-man" ham station using a variety of antennas, including the Chameleon Hybrid Mini and the P-Loop Magnetic Antenna.  This video was shot at the 2016 ARRL Field Day when propagation was beginning its slow decline from previous years.  Despite t

Vertical antennas are a good choice for many portable and home ham radio stations. But, how well do these antennas actually perform in the field?  In this video, N5CFB, KG5PWA, and K5ACL test three popular vertical antenna designs.  While all antennas performed well, some were easier to match and operate than others.  Interesting "live" test.

Antenna research continues forward as radio amateurs take advantage of newly permitted operations in the 630 meters and 2200 meters (475 kHz and 137 kHz) amateur radio bands.  As this video from "hellozerohellozero" points out, size isn't the only concern of those operating far below the standard broadcast band.  Weather and other environmental issues can make use of these new bands a bit challenging. In this video, we get a glimpse of what one Alaska (KL7) ham is doing to keep his low frequency antennas operational.  All of this takes place with a stunningly beautiful look at Alaska's natural beauty.  Enjoy!

Accessed on 15 April 2018, 2125 UTC, Post #1463. Please click link to read the full story. Comment: Why not try a new antenna for the upcoming ARRL Field Day on 23-24 June 2018? The compact HF multiband antenna described by NC4FB may be what you're looking for.  This antenna is based on a design my G7FEK (http://www.g7fek.co.uk/software/G7FEKantenna.pdf) and will cover all Amateur Radio bands between 80 and 10 meters. An antenna transmatch (i.e. "tuner") is required for 17, 15, 12, 10, and 6 meters. According to NC4FB, this compact antenna has several good points in its favor: Small size Uses 50 ohm coax as an antenna feeder. Multiband operation between 80 and 10 meters. Low angle of radiation (good for DX). Easy to build, set up, and take down. This antenna can fit on most urban lots and
