A simple vertical antenna can be an amazingly effective way to launch your signals, especially if you lack the space to erect a dipole, inverted vee, or even a small yagi-uda beam.  In this video. Ric (K8YIO) show us his simple vertical antenna and ground radial system. Most of the materials can be found at the nearest hardware or building supply outlet.  This simple antenna has given Ric plenty of DX.  The video is loaded with lots of suggestions that will help you design, build, and use this antenna at your home station.

Here's a low-cost answer to a common problem shared by shortwave listeners and radio amateurs. Namely, how to connect one antenna among several radios. The answer is found in a simple HF Antenna Splitter that you can build yourself. The HF splitter is for listening only.  The splitter is not intended for transmitting. "The Radio Hobbyist" has done an excellent job of showing the assembly of this simple, useful tool.  While you can find HF splitters online, you may want to save some money and build one yourself.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=I_VmFGVAR7k, NVIS (near vertical incident skywave) antennas are perfect for local, state, and regional communications during portable or emergency operations.  NVIS antennas radiate signals at a high angle, making them ideal for coverage out to approximately 300 miles/486 kilometers.  I've used low-slung dipoles (approximately 17-feet/5.182 meters above ground) for local Hawaii nets and rag chews around the state. In this video from "Commsprepper", we learn how to set up a basic NVIS antenna based on a design from W9WIS (http://w9wis.us/NVIS.html). This antenna is simple, easy to erect, and inexpensive.  Other NVIS antennas can be configured as tuned end-fed wires, low level loops, and even magnetic loops. Have some fun and build a NVIS antenna today. For the latest Amateur Radio news and information, please check these websites: http://w

I always enjoy the "laid back" and relaxing manner in which Dave Casler presents his video tutorials. This one is no exception. In this video, Dave explains how to make and use a simple 40-meter dipole antenna from commonly available parts around your shack or home. Other materials can be found at the nearest building supply or hardware store.  In this case, Dave was able to make this antenna at no cost, thanks to the materials he had in his home. This is a classic case of time vs. money.  If you're willing to spend a few hours of free time making this antenna, you'll save money and have a lot of fun at the end of your labors.

If you can't views this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v-JnKjPIOI7Tg. Every radio amateur should have an emergency backup system in his/her shack. In this video from Joe Lalumia ("Telescope Man"), we see a simple arrangement of spare equipment that allows emergency operation when natural or human-made disaster strikes. Radios in use are a Kenwood 281 for 2 meters, an ICOM-7200 for HF, and a handheld Uniden scanner receiver for monitoring the public service bands.  Joe's antennas include a Buddipole, MFJ hamsticks for various HF bands, an Alpha-Delta DXCC, a QSO King, and a dual band cushcraft 270.  Perhaps this video will encourage you to create your own backup system in your radio room.
