Simple Ham Radio Antennas--DX80 HOA Hell stealth setup. Post #762.


If you're having difficulty viewing this video, please insert this title link into your brower search box: https://youtu.be/0nsomb-V-3s.  Operating in a HOA/CC&R restricted area presents some unique challenges.  Antennas must be "stealthy" (unseen), simple, easily deployed, and quickly taken down if suspicions are raised by your neighbors.  While this stealth installation of a RadioWavz 80 OCF (off center-fed) dipole is a bit complicated, it can be done quite quickly if you plan carefully and avoid prying eyes during the installation phase.  Please note how this radio amateur uses a privacy fence, trees, and property geography to hide this antenna from public view.  Although this antenna arrangement won't beat a 3-element yagi on the bands, it will get you on the air with a decent signal without being seen.  A basic rule applies:  Out of sight, out of mind.  Good luck.

Simple Ham Radio Antennas--Underground HF Antenna, 40 meter Loop-Survival Podcast. Post #761

Underground HF Antenna, 40 meter Loop--Survival Podcast
(https://thesurvivalpodcast.com/forum/index.php?topic=51280.0).
Accessed on 30 April 2016, 02:06 hrs, UTC.
Reporter:  Carl, "Mr. Ham Tastic."

Comment:

If you need the ultimate stealth antenna, why not use a subsurface 40 meter loop suggested by the author of this intriguing article?  For a slight sacrifice in receive strength, you can get a reduced noise level plus the added attraction of using an "invisible" antenna.  Carl built a 154-foot/46.95 meter loop and placed in beneath his yard.  The antenna is quiet, nearly invisible, and fairly cheap.  Although you do get a signal that's 2-3 dB below a regular dipole, regular noise is reduced considerably, so the trade-off may be worth pursuing.  Underground antennas have been used for years by the world's major military powers, and there is no reason why you can't discover the benefits of this antenna as well. Other ground-mounted antennas can work fairly well on the lower HF and MF broadcast bands.  For the latest Amateur Radio news and events, please check ou the blog sidebars.  These news feeds are updated daily.  Thanks for joining us today!

Simple Ham Radio Antennas--Ham Radio MARS Counter Poise Ground Saturn Dipole Antenna


If you're having trouble viewing this video, please insert this title link into your search box: https://youtu.be/J9a1mAAtSbE.  This easy to understand video from http://www.radiowavz.com shows how adding a simple counterpoise or radial ground system can greatly enhance the quality of an antenna.  A good ground radial system is especially important for vertical antennas, since the radial system supplies "the missing half" of a vertical antenna system.  The intent of the video is to show that radials do make a difference in antenna performance.  I'll cover the "nuts and bolts" of ground radial systems in a future post.  But, for now, this video gives you an indication of just how important a ground radial system is to most antennas.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  Thanks for joining us today!

Backpack amateur radio. Post #759


If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/bdCCw0qu5-g.  With the ARRL Field Day set for 25-26 June 2016, it may be a good idea to go "into the field" and test your portable and emergency gear.  Even if you don't join a club for this effort, individual and home stations can enter one of the biggest emergency preparedness exercises of the year.  A little practice beforehand will get "you in shape" for the big event.  Besides, backpacking with amateur radio is fun and educational.  In this well-done video, we see how Simon (2E0CRV) prepares his backpack radio station for a hike "into the field."  His system is simple, efficient, fairly lightweight, and easy to set up in a remote location.  Although Simon is using the versatile Yaesu FT-857D transceiver, you can use what you have available in your shack.  In my case, I use an "oldie, but goodie" from the distant past (Yaesu FT-7) for my portable and emergency rig.  You can use a variety of power sources and easily- made antennas for this project.  Simon offers a lot of helpful hints on setting up a portable backpack ham station.  Once you assemble your backpack system, take it out to a public park, beach, or campground and try a few contacts.  In Simon's case, he had some interesting QSOs with Argentina, the USA, Brazil, and Asiatic Russia. You may want to keep this backpack radio system in your vehicle for portable or emergency use should the need arise.  For the latest Amateur Radio news and events, please check out the blog sidebars.

Simple Ham Radio Antennas--Backward Inverted L Antenna. Post #750


If you're unable to view this video, please insert this title link into your browser search box: https://youtu.be/SOpdXHnzwIA.  Here's another interesting antenna idea from Stan Gibilisco (W1GV)--something he calls a "Backward Inverted L Antenna."  While this antenna is designed primarily for receiving purposes, it can be modified to transmit on all amateur radio bands between 160 to 10 meters.  As with all verticals, a good ground radial or counterpoise system is necessary. I've built a few of these antennas and they work very well on 160 meters and on the MW standard broadcast band.  You can also use this antenna for general short wave listening when your amateur radio activity is done for the day.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).

Simple Ham Radio Antennas--An All Band Loop. Post #749.

An All Band Loop Antenna
(http://www.eham.net/articles/36087).
Accessed on 17 April 2016, 05:37 hrs, UTC.
Author:  Howard Walker (KI4VEO).

If you have a large lot and want to experiment with the properties of loop antennas, then this article from Howard Walker (KI4VEO) may be what you need. Since Howard was blessed with several tall trees on his 4-acre property, he decided to string up a full wave loop antenna covering the amateur radio bands between 160 meters and 10 meters.  Howard ended up with a 570-foot/173.78 meters wire loop antenna that brings in plenty of DX during his time on the air. In this article published on eham.net, Howard discusses the construction techniques and the equipment needed to erect this large loop antenna. I've used full wave loop antennas in the past, albeit not as large as Howard's project.  My current 40 meter delta loop is fed with 450 ohm ladder line into an antenna transmatch (i.e. "tuner").  This modest antenna does an excellent job on all amateur radio bands between 40 and 10 meters.  If you choose to erect a large loop antenna following Howard's example, be sure to get the help of a few friends.  This will be a huge undertaking.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.

Homemade dummy load. Post #747.


If you're having trouble viewing this video, please insert this title link into your browser search box: https://youtu.be/Yx5F1jUFySM.  Here's a simple project that you can assemble in your spare time that will help you adjust your transceiver without going on the air and creating needless interference.  A dummy load is a basic piece of equipment that every radio amateur should have in his/her shack.  Although you can buy commercial models, it's more fun and educational to "roll your own."  In this video, "the250rider" shows us how common items around your home and shack can be converted into a practical and cheap dummy load.  The resistor network consists of 8, 100 ohm-1/2 watt 5% tolerance resistors run in a series/parallel circuit.  You can keep the resistor network cool by immersing it in a jar of vegetable oil.  According to "the250rider", this homebrewed dummy load has a measured impedance of 49.8 ohms, close enough for casual use with connecting 50-ohm coaxial cables.  Although this dummy load can take up to 200 watts for a few seconds, it's best to use this device at power levels around 50 watts or less.  For the latest Amateur Radio news and events, please check out the blog sidebars.  These news feeds are updated daily.  Thanks for joining us today!  Aloha es 73 de Russ (KH6JRM).

An exceptionally well-done video by Ms. Valerie Hotzfeld on the historical background, construction practices, and varieties of Beverage Antennas available to radio amateurs.  Her description of the antenna's inventor, Harold H. Beverage, is particularly good. This antenna is worth considering if you are serious about working the 160 meter band ("Top Band").  As a receiving antenna, the Beverage can't be beat.  Of course, this type of traveling wave antenna requires a lot of space and it's not for everyone.  But once you've used a Beverage Antenna, you won't try any other type of receiving antenna for 160 meters.  I have one installed on my vacation home in the Puna District of Hawaii Island and I find it's a super performer on the MW standard broadcast band as well as on "Top Band."
