During my career in commercial broadcasting, I've climbed enough towers to last a lifetime. The fact that I'm still alive to discuss such things is a tribute to my training, the use of certified safety equipment, pre-planning, and plenty of help on the ground. In this video from Valerie Hotzfeld, we learn how to climb ham radio towers safely. The emphasis of this video is on planning, safety equipment, and adequate ground support.  Don't take shortcuts when you climb towers.  Just take your time and work slowly.

Not all mobile operations can be run from your vehicle.  How about mounting a simple 5/8 wavelength Larson VHF magnetic mount antenna on your bicycle and using a HT to contact fellow radio amateurs on 2 meters while you cruise around the neighborhood?  "Taverned" has just done that with a simple 2 meter mobile antenna arrangement on his mountain bike. When you've finished your run, you can park the bike at a public park and operate portable from a bench or picnic table.  A very simple, effective operation--plus you get exercise and some fresh air at the same time.

Placing your ham radio antenna atop a mast can really boost your your antenna performance, especially if you're using a small yagi beam. In this video, "ColdMoon" shows how he erected a mast by himself using 3 guy lines and a fiberglass pole.  While this arrangement works, it may be safer to have a friend help you, in case there is a problem.

My Isotron 10 Meter Ham Radio Antenna. Post #1195.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=MxskjoxWi1A. If you want to experiment with an unusual antenna design, try the Isotron 10 Meter Ham Radio Antenna.  In this post from "videosbymike" we see how this antenna is built and what it can do when propagation favors the 10 meter band. Mike unpacked the box, quickly set up the antenna, and made some solid contacts to Santiago, Chile and Puerto Rico from his porch approximately 20-feet/6.097 meters above ground.  The rig used for the antenna test was an old Radio Shack HTX-10 running 25 watts from solar panels.  Isotron also makes antennas for 160, 80, 40, 20, and 15 meters.

2E0WMG Vertical Antenna Building. Post #1194.

If you can't view this video, please enter this title URL into your browser search box: https://www.youtube.com/watch?v=jiHKFAdu18U. You don't need a lot of expensive equipment to get your HF rig on the air.  In this video from Kevan (2E0WMG), we see how a few feet/meters of wire, a fiberglass telescoping pole, and a simple ground radial/counterpoise system can provide an easy entry into the HF band of your choice.  The use of an antenna transmatch (i.e. "tuner") will give you some flexibility and better control over the SWR you'll experience on this antenna.  This easy to make vertical antenna can be used at your home or in the field for portable or emergency operations.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=oIoLbe968Cg. Here's an antenna project that could get you some additional gain and directivity on the HF band of your choice.  Because of size considerations, BYRONLOCAL decided to design, build, and use a 15 meter extended double zepp antenna for his ham station. The extended double zepp is a collinear array of two 5/8 waves in phase.  This video provides an excellent overview of the theory and construction practices used to build this antenna. Applicable formulas and scale drawings are provided to guide you in the construction of this antenna.
