It may be wise to make several versions of this simple, inexpensive antenna for portable or emergency operations.  Kevin Loughin (KB9RLW) does an excellent job of creating an emergency antenna from coaxial cable.  The antenna is easy to build and uses a minimum of tools.  The antenna can be designed for your favorite amateur radio bands and stored in your vehicle or shack when you need to get on the air quickly.

Here's an antenna you may want to try in your spare time.  In this video, Stan Gibilisco (W1GV) presents the theory and operational parameters behind this rarely used but effective antenna. This antenna can be used where a tower and metal beam antenna aren't feasible.

Antennas in the Attic: Ham Nation 215. Post #1239.

This excellent video with Gordon West (WB6NOA) comes from the Ham Nation program, episode 215.  In this video, Gordon shows how radio amateurs remain active by placing a variety of antennas in their attics.  Sometimes, there are no other alternatives because of deed-restricted housing (HOAs and CC&Rs). A few of these compromise antennas work quite well, delivering hours of operating time to antenna-limited areas.  Hopefully, some of these suggestions will help you get and stay on the air.

Here's a simple, efficient, and inexpensive HF dipole antenna that covers 80 meters to 6 meters.  The key to multiband operation is the use of 300 ohm twin lead as a feeder and a 1:1 ATU balun.  You can also use 450 ohm ladder line or home made balanced line into a 1:4 current balun and then connecting the antenna feed line and balun to an antenna "tuner" with a short length of 50 ohm coaxial cable.  W5XJ provides a list of easily obtainable materials for this versatile antenna.  If you have only one tall support, you can configure the antenna as a dipole "sloper" antenna.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=oYg9jbdjTIw. Excellent, well-paced video from "Musings" showing us one way to convert a 5/8 wave CB antenna for ham radio use.  Depending on your interests, this video can help you transform an old 11 meter (CB) antenna into an effective vertical antenna for 20, 15, or 10 meters with just a few shop tools and a little imagination. I've converted a few 108-inch/274.32 cm CB whip antennas (from Radio Shack) into usable 10 meter vertical antennas without much difficulty. While this video has a bit of a learning curve, it shouldn't be too hard to copy the procedures shown and build your own, inexpensive HF vertical antenna from unused or discarded CB antennas.
