If you use a "long" or "random length" wire for your HF antenna, you'll probably need a simple antenna transmatch (i.e. "tuner") to reduce SWR and RFI caused by the mismatch between your antenna and your transceiver. In this well-produced video, Kevin Loughin (KB9RLW) takes us step-by-step in the design, construction, and use of a simple L tuner for random length wire antennas.  This basic impedance transformer can be used at home and for field operations.  Views expressed in this video are those of KB9RLW.

In this video from Randy Hall (K7AGE), we learn how to use the popular MFJ-259/269 Antenna Analyzer to check your antenna for SWR and Resonance.  This fairly inexpensive tool will come in handy the next time your build a new antenna or maintain your current "skyhook."  Randy does an excellent job of explaining how the MFJ-259/269 works and what you can expect to gain from using this device.  Views expressed in this video are those of Randy Hall (K7AGE).

7 MHz WSPR with a kite supported vertical antenna. Post #1451.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=SgN2FcMYL80. Here's another great antenna idea from Australian radio amateur Peter Parker (VK3YE).  In this video, Peter tries a kite supported antenna to launch his WSPR signal.  WSPR can work with inefficient, short antennas, but really shines when you attach your rig to a half wavelength vertical antenna.  Peter says his 200mW signal was received in North America and the Canary Islands...great distance for a QRP signal.

Sooner or later, you'll want to build a simple beam to increase your rf "footprint".  If you live on a small urban lot or in an area with restricted space, building a beam can be quite a task.  In this video, GW0JXM show us how to design, build, and use a simple 2 element beam for the 20 meter amateur radio band that is both easy to raise and take down while still fitting in a small space.  The video contains many helpful suggestions, including a materials list and construction tips.

A nice, laid back antenna tutorial from "DX Commander" as he describes his first amateur radio antenna--a delta loop mounted 7 meters (22.96 ft) above ground.  This antenna produced great results for him during his first years as a licensed radio amateur. In this video, "DX Commander" shows you how to design, build, use, and test a simple delta loop antenna, which can cover several amateur radio bands with a balanced feedline and an antenna "tuner."  Delta loops are easy to make, exhibit low noise on receive, and can be designed to be "stealthy" in crowded neighborhoods.
