If you're having trouble viewing this video, please insert this URL into your blog search box: https://youtu.be/Z6ATX29ews.  A well-done and enthusiastic video by Rockwell Schrock as he builds a DIY Buddipole HF Antenna.  The design is based on a pattern developed by Budd Drummond (W3FF).  A complete set of plans for this antenna can be found at:  https://sites.google.com/site/w3ffhom.  I like Rockwell's enthusiasm for homebrewed antennas and his definite "can do" attitude.  The project is perfect for a portable or emergency antenna.  For the latest Amateur Radio new and events, please check out the blog sidebars.  These news feeds are updated regularly.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM)...along the Hamakua Coast of Hawaii Island.

Simple Ham Radio Antennas--5 Min Emergency Antenna. Post #528.

If you have trouble viewing this video, please insert this URL into your browser search box: https://youtu.be/XgyH6JQ3XHo.  This short video by Jerry H. Kolins shows you how to make a quick and easy emergency antenna in about 5 minutes.  The outer shield of the coaxial cable becomes the "missing half" of a 1/2 wave dipole antenna.  In effect, you're making a vertical "sleeve" dipole. Due to the lengths involved, you may want to confine such antennas to the 20 meters to 10 meters amateur radio bands.  These antennas also work well for 2 meters.  For the latest Amateur Radio news and events, please check out the blog sidebars.

If you have difficulty viewing this video, please enter the following URL into your browser search box: https://youtu.be/KbEyvp-0eQY.  Here's an unusual way of getting some decent directivity and gain from a vertical antenna system.  In this homemade video from Bob (W04O), club members used a three-element vertical "half yagi beam antenna " to contact Japan from Kansas City .  Last year I made a three-element vertical yagi on my houselot in the Puna District of Hawaii Island .  The missing half of the yagi is supplied by a ground radio or counterpoise system. In this video, club members are using three S9 Antenna masts to support the vertical elements.  These mast are flexible and can be telescoped down to a fairly short length--perfect for portable and emergency operations.  On my "antenna farm", I used three 16-foot/4.87 meters lengths of schedule 40 PVC pipe to support elements for 15 meters.  The radial system was attached to the shield of the RG-8X

. If you have trouble viewing this video, please insert this URL into your blog search box: https://youtu.be/ebAjdBpU5RA.  Good tutorial from "the Casual Citizen" on how to build a "go box" for emergency or portable use.  The convenience of having all of your radio equipment stored safely and easily transportable "just makes sense."  Couple the "go box" with a solar powered 12 volt battery, a portable antenna (such as a BuddyPole),  an antenna transmatch (i.e. "tuner"), and a portable rig (VHF/UHF, HF) and you have a complete ham radio station that can be taken with you.  This would make an excellent weekend project.
