Thanks to Kevin Loughin (KB9RLW) for this amazingly simple, cheap, and high performance vertical antenna.  Kevin originally designed this homemade antenna for the ARRL Field Day, where the accent is placed on emergency power, quickly made antennas, and the ability to handle contacts in a simulated emergency setting. Materials for this portable vertical HF antenna can be found at the nearest building supply outlet or neighborhood hardware store.  If you have extra coaxial cable and a telescoping fiberglass mast, your construction phase will go fairly quickly.  Why not make one of Kevin's antennas for your "go-kit" or for portable, "in-the-field" expeditions to the nearest park or recreation area? Also, you could make this antenna for home use, should your regular HF antennas be out of service. For the latest Amateur/Ha

Stan Gibilisco (W1GV) does an excellent job of explaining the pros and cons of Balanced and Unbalanced Feed Lines, or what Stan calls "symmetrical vs asymmetrical feed lines."  Each type of feed line has both advantages and drawbacks, depending on what kind of antenna you use. For monoband use, a coaxial cable feed line is often the best solution.  However, if your antenna is designed for multiple band use, a balanced feed line such as 450 ohm ladder line, 300 ohm television twin lead, or even homemade 600 ohm balanced line used with a wide-range antenna transmatch (i.e. "tuner") is often the better choice from the standpoint of line loss and SWR.

Frank Donovan (W3 LPL) presented this informative, excellent antenna tutorial at the January 2016 meeting of the Frankford Radio Club. Frank offers helpful, valuable suggestions on how radio amateurs can maximize the performance of their antennas in the lower HF bands during a period of uncertain propagation.  Frank discusses antenna polarization and the need for both receiving and transmitting antennas for 160 and 80 meters. Frank's program would make an excellent presentation for any amateur radio club or for an amateur radio license class.  Frank's tutorial is clear, concise, and easy to follow.

Here's great project for those wanting a separate receive antenna for both Amateur Radio and general shortwave listening.  The antenna covers 5 MHz to 14 MHz--enough flexibility to include all amateur radio bands between 60 meters and 20 meters. This antenna is simple, cost effective, compact, and suitable for indoor operation. The addition of a classic Hallicrafters S-38 receiver rounds out an excellently produced video.
