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!

Compact Multi-band Field Day Antenna (80-10 meters). Post #1463. http://www.nc4fb.org/wordpress/compact-multi-band-field-day-antenna-80-10-meters. Author:  NC4FB. 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

Here's a simple, inexpensive, and effective dipole antenna you can use for the 10 meter band during the ARRL Field Day in late June.  According to "Tanner Tech", the antenna sets up in 10 to 15 minutes and uses the wheel of the truck to support a mast.  You can modify this antenna for any other amateur radio band.  This antenna is suitable for both portable and home station use.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=yH0zKNNGa0s. In this video, Kevin Loughin (KB9RLW) shows us how to make a simple, cheap, and effective HF antenna for the upcoming ARRL Field Day (23-24 June 2018).  All you need is some wire, a 9:1 balun, a telescoping fiberglass mast, a simple ground radial system, and an antenna transmatch (i.e. "tuner") to create a portable multiband HF antenna for your next portable or field operation. Kevin says this homemade vertical antenna works very well and will get you on the air quickly with little cost. Views expressed in this video are those of Kevin Loughin (KB9RLW).

K7PP's Multiband Fan Dipole Project Ham Radio. Post #1459.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=SXqSY5JKQzs. While this antenna from K7PP will prove to be a bit challenging for a Field Day operation, it could be ideal for a home site with plenty of room.  Fan dipoles using a common feed point attached to several band specific antennas have been popular for decades.  The elimination of an antenna "tuner" could be an advantage for those who prefer separate dipoles but can only use one feed line. K7PP designed this antenna to cover 80, 40, and 20 meters with one feed line.  Ten meter operation is possible using a harmonic of the 80 meter band. Views expressed in this video are those of  K7PP.

Balloon Antenna Field Day 2016. Post #1458.

If you can't see this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=GEDneotW3ko. Here's an interesting antenna idea for those seeking a good 160 meter antenna for the upcoming ARRL Field Day in late June 2018.  How about using a balloon-supported 1/4 wavelength antenna for "The Gentlemen's Band?"  Be sure to plan ahead and check with your local airport to make sure your balloon-supported antenna doesn't present a threat to low-flying aircraft.  According to the "Ham Prepper" team, this balloon-supported antenna did very well that weekend two years ago.
