Over the past few years, I've featured several videos and extended articles on mobile operations using amateur/ham radio.  The one area I didn't cover was how to install amateur/ham radio equipment on a boat.  Boat mobile seems like an interesting way to contact our fellow radio amateurs.  In this video from Captain Cefus McRae, we see how to install a VHF transceiver and antenna on an open water vessel.  If you take your boat on a lake or even into the ocean, it pays to take along a VHF transceiver and some amateur/radio equipment just in case you run into an emergency.  This video offers a quick, simple installation that will make sure you have emergency communications handy when you need them.

Bobtail Curtain Antenna. Post #1623.

A Bobtail Curtain Antenna is something you should try at least once in your Amateur/Ham Radio "career."  I've used "curtain antennas" during ARRL Field Day events, and can attest to their high directivity and gain.  Simply stated, a Bobtail Curtain Antenna is a bidirectional, monoband wire array that can really add "punch" to your signal.  Stan Gibilisco (W1GV) does a good job of explaining the theory, construction, and use of these high-gain antennas.  If you have a spare weekend and a friend or two to help you, please build and test your own Bobtail Curtain Antenna. You may be surprised just how well this array performs.

Top Band Hams-22 Different Wire Antennas for the 160 meter band. Post #1622.

Top Band Hams-22 Different Wire Antennas for the 160 meter band. http://topbandhams.com/?id=6. Accessed on 21 September 2018, 0441 UTC, Post #1622. Please click link to read the full article. Comment: During the current solar cycle, propagation seems to favor the lower HF bands from 160 meters to 40 meters.  This may be a good time to build some antennas that take full advantage of  the "Top Band" or 160 meters.  Thanks to the Top Band Hams group, we have 22 proven designs that will provide you with hours of good contacts during this period of poor propagation on the upper HF bands (20 through 10 meters).  Each antenna is fully illustrated with all necessary measurements included. Here are some of the antennas covered in this excellent tutorial: Random Length Radiator Wire Antenna. Delta Loop Antenna. Half-Delta Loop Antenna. 1.9 MHz Full-Wave Loop Antenna. Off-Center-Fed Full-Wave Doublet. Terminated Sloper Antenna. 40-80-160 Multiband Short Dipole Anten

Antenna experiments are fun, educational, sometimes surprising, and at times frustrating.  In this video from "umajunkcollector:, we see a variety of curious and fascinating homemade HF antennas that work very well for the bands they cover.  Particularly interesting are the inverted U antenna, an inverted V slinky dipole antenna, and an unconventional 20 meter antenna.  Try some of these antennas and see how well they perform.  Most of the antenna materials can be found in your junk box or from the nearest building supply outlet.  Building antennas is a great way to spend a creative afternoon.

G5RV Multi Band HF Dipole. Post #1620.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=aeNHIQ_j4Dk. Although Louis Varney (G5RV--SK) designed this antenna as a 3/2 wavelength dipole for the 20 meter band, it has proven useful on amateur radio bands from 160 through 10 meters.  In this video, Bernie Huth (W4BGH) explains the basic theory, design, construction, and use of this multiband antenna.  Bernie presented the original video to the Brandon Amateur Radio Society in Brandon, Florida in March of 2017.  The video is exceptionally well made and includes valuable suggestions for making this versatile antenna.
