Simple Ham Radio Antennas--Portable HF Ham Radio Antenna. Post #448


If you have trouble viewing this video, please enter this URL into your browser: http://youtu.be/642N0oWgY5I. A nice, simple tutorial from W0ZF on how to make an inexpensive portable vertical antenna for the 20 meter Amateur Radio Band. I've made a few of these antennas using a fiberglass telescoping mast, some #18 AWG speaker wire, a few insulators, a simple ground radial systems, an appropriate length of RG-8X coaxial cable as feed line, and an antenna transmatch (i.e. "tuner") to keep the SWR to a low level. If you wish multiband use of this 20 meter vertical antenna, you can feed the antenna with balanced line (450-ohm window line or 300 ohm tv twinlead). The balanced line would go into a 4:1 balun and then onto your antenna transmatch using a short length of RG-8X coaxial cable. This simple antenna works.
