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.

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.

"Radio Prepper" does an excellent job of taking us through the design, construction, and use of a simple 6-element Yagi-Uda antenna for the 2 meter Amateur Radio band.  The original design can be found at this website: https://m0ukd.com/homebrew/antennas/144mhz-2m-portable-yagi-vhf-beam-antenna. This antenna can be used at your home station or for portable or emergency operations.  If you have difficulty reaching a repeater in your area, this antenna can help resolve that issue.  Depending on how you orient the antenna (horizontal or vertical), you can use this yagi for 2 meter SSB contacts, which tend to favor horizontal polarization.

Here's another great and instructive video tutorial from Julian (OH8STN), whose "Survival Tech Nord" website provides a treasure trove of practical ideas and projects for the radio amateur. In this video, Julian shows us his Ham Radio Go-Kit, something that all radio amateurs should have in case of emergencies.  Julian's Go-Kit is built around the popular Yaesu-817ND qrp transceiver and the Chameleon Antenna MPAS (modular portable antenna system).  This portable ham radio station is great for training, emergency communications, and just plain radio fun in the great outdoors.

Bicycle mobile is a fun way to enjoy the great outdoors and get on the air at the same time.  In this video, Steve (WG0AT), sometimes known as "The Old Goat", equips his mountain bike with a battery, a 6 meter Buddipole antenna, and an old IC-703 QRP rig.  The video shows some fascinating contacts on the road, including Randy (K7TQ) in Moscow, Idaho operating pedestrian mobile.

This video tutorial from Hank Ottey does an excellent job of explaining RF and Antenna Basics as they apply to 802.11 wireless systems. The tutorial covers two broad areas: Aspects of Antennas (gain and signal speed; reciprocity; range; and mounting). Enemies of Signal Quality (multipath; obstructions; Fresnel Zones; and weather). Each section is well-illustrated with graphs, photos, and other data.

HF J-Pole (http://www.eham.net/articles/39180). Accessed on 25 July 2017, 20:00 hrs, UTC. Author:  Mike Higgins (K6AER). Please enter link into your browser search box to read the full article. Comment: Most radio amateurs are acquainted with the J-Pole antenna, which finds a ready application for our shared VHF/UHF bands.  The antenna is simple, easy to make with commonly available materials, and provides a modest amount of gain. In this post, Mike Higgins (K6AER) describes the HF version of the J-Pole antenna scaled for both 20 and 40 meters. He briefly describes how the antenna is designed and built: "There is nothing special about a J pole, it is an end fed ½ wavelength vertical radiator that needs no radials. Just like its 2-meter brother but on 20 meters it is ten times larger. The bottom ¼ matching section is fed with 50-ohm coax. Bottom of the antenna is shorted and the coax attaches at the 50 ohm point in the matching transformer. The higher the attach...
