The antenna use a UnUn (unbalanced to unbalanced) balun to insure a good match between feed line and antenna.  Kevin says this antenna is perfect for QRP operations.  You may want to build one of these antennas for emergency or portable use.  This would make a great stealth antenna as well--easy up and easy down with only a small visual impact.

If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/sUcO6LrPtmM. Here's another great idea for a nice, inexpensive, and easily-assembled multiband HF antenna.  In this video, Tony (KD8RTT) shows us how 100-feet/30.48 meters of 24-gauge speaker wire can be used to make a simple, effective HF antenna covering several amateur radio HF bands.  Tony uses a LDG Z-100 antenna transmatch (i.e. "tuner") to match his transceiver to the antenna.  A 4:1 current balun could be used with a coaxial cable feed line or a 1:1 current balun with ladder line to keep losses low and to protect your transceiver  from damage.  A great antenna for portable or emergency operations.

Simple Ham Radio Antennas--VP8STI South Sandwich Island video on web. Post #813

VP8STI South Sandwich Island video on web (https://vimeo.com/intrepiddxgroup). Accessed on 21 June 2016, 19:45 hrs, UTC. Reporter:  http://www.southgatearc.org. Please click link to view the video. Comment: A well-produced video from the Intrepid DX Group documenting the successful DX-pedition to South Sandwich Island (VP8STI) earlier this year.  Considering the awful weather, high winds, and the unforgiving land mass which served to anchor the DX-pedition, the trip to this near Antarctic island group was quite a success. I just got the shivers from watching this video--that place is very cold and wet even in the Southern Hemisphere's "summer" season.  Although I was unable to contact the VP8 crew, I followed some of the QSOs and was glad the island crew did their best to keep QRM to a minimum.
