Here's another interesting approach for making a portable or emergency HF antenna covering 6 through 80 meters. "Survivalist2008"calls this antenna his "Fishing Reel" antenna because most of the components are stored on a fishing reel and can easily be carried in a backpack. "Survivalist2008" says this homebrewed off-center-fed dipole antenna is stealthy, lightweight, and can fit into a pocket on his knapsack.  In part one of this video, we learn what materials are needed make the antenna and the construction steps necessary to get the antenna operational. In part two, we will continue building the antenna and learn how to maximize its performance in a field operating situation.

If you wish to explore antenna possibilities beyond simple dipoles, inverted vees, and verticals, try building a yagi, log periodic, and phased array. The time and effort expended in designing, building, and using these antennas is worth it in terms of better performance, higher gain, and directivity. In this video, Dave Casler (KE0OG) discusses each of these antennas and makes suggestions on how you can build your own version of these antennas. The video is informative and easy to understand--a good, basic tutorial worth keeping in your reference library.

If the current solar cycle is making HF operations difficult and tedious, why not try some of the Amateur Radio microwave bands, such as the popular 10 GHz Band (X-Band)?  Equipment is readily available and instructional videos such as this one are available online.  With the advent of improved antennas, better transceivers, and manageable power supplies, it's possible to make many daily contacts via EME, meteor scatter, and knife-edge refraction. In this video, Gordon West (WB6NOA) and Tim Tucker (AE6LX) demonstrate the antennas, feed lines, transceivers, and operating procedures that will insure you success on this microwave band.

If you can't views this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=PiU6x9aZT7A. I'm familiar with steel tape measures as elements for 2 meter yagis, but I've never seen the same principal applied to the HF bands.  In this video from KI4PMI and NC4FB, we see how common steel tape measures can be used for antennas covering 40 through 06 meters.  According to NC4FB, you change bands by adjusting the length of the steel tape measure. An ingenious, creative, and inexpensive way to use common materials as antenna elements.  This antenna covers amateur radio frequencies from 40 through 06 meters.  You can have plenty of fun working with this type of antenna.

The 80m Amateur Radio Band & NVIS. Post #1302.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=NABWhIHJwdc. If you enjoy portable operations and find it difficult to contact stations on 80 meters, you may want to make a NVIS (near vertical incident skywave) antenna covering this great "rag chew" and daytime regional band. In this video, Gil (Commsprepper) shows us how to make a simple NVIS antenna that delivers excellent local, state, and regional coverage up to 400 miles/648 km.  This video shows Gil's 135-foot/41.15 meters NVIS antenna suspended over a wooden bridge.  He reports excellent local and regional coverage from this simple installation. Eighty meters is an excellent band for portable and local emergency operations.
