Simple Ham Radio Antennas--W5TOM Stealth Antennas. Post #850.


If you're having trouble viewing this video, please insert this title link into your browser search box:' https://www.youtube.com/watch?v=1UgoY2nvUds.  In this video, Tom Morton (W5TOM) discusses several antenna configurations suitable for deed-restricted homes or apartments. Tom shows how easy it is to disguise a vertical, loop, inverted V, a dipole, and a random wire antenna so that it remains undetected by neighbors.  Tom also reviews the importance of using a good rf ground, a sturdy antenna transmatch (i.e. "tuner"), and a fool-proof wire launching system. He briefly touches upon the use of a lightweight telescoping fiberglass mast to support vertical and inverted V antennas.  This video should give you a few good ideas on how to design and use your own stealth antenna. Remember the old saying:  "Out of sight-out of mind."

Simple Ham Radio Antennas--W5TOM Field & Emergency Antennas. Post #848.


If you're having trouble viewing this video, please insert this title link into your browser search box: https://www.youtube.com/watch?v=AMwRZVi-IOA.  If you need a cheap, effective emergency antenna for portable or home operations, then this video from Tom Morton (W5TOM) may help you reach that goal.  In this video, Tom discusses the various pieces of equipment you'll need to assemble and build an emergency antenna that is cheap, durable, and effective. Tom reviews several antenna "tuners" that will help you match the antenna to your rig, offers suggestions on wire sources, describes several antenna launching schemes, and offers several coaxial connectors that will help you interconnect your equipment to the antenna.  Tom then demonstrates several designs at a public park and at his home.  An excellent video for antenna experimenters.

Comment:

An excellent slide show presentation on the use of the Raspberry Pi microprocessor for amateur radio projects.

This well-done slide program was presented to members of the River City Radio Communications Society this month by Keven Hooke (KK6DCT).

The program consists of 31 slides which describe how you can integrate the Raspberry Pi microprocessor into various phases of your amateur radio operation. Most of the projects are simple, inexpensive, and fun to use.

Simple Ham Radio Antennas--More Magnetic Loop Antenna Work. Post #846

More Magnetic Loop Antenna Work

Comment:

One of my favorite amateur radio websites is the QRP blog published by New Jersey ham, Larry Makoski (W2LJ).  He's always trying new things and isn't afraid to experiment with antennas, accessories, and rigs.

In this post, Larry describes his progress in making a QRP magnetic loop antenna tuned by a "homebrewed" capacitor box of his own design.  Magnetic Loop antennas are excellent for space-restricted radio amateurs or for portable operations.  Tuning magnetic loop antennas can be tedious because of their narrow bandwidth.

In years gone by, one could buy surplus Jennings air variable capacitors and be operational in no time.  Although these capacitors were often available, their cost discouraged many amateurs from using them.  Since then, there have been numerous tuning schemes using everything from coaxial cable to "homebrewed" capacitor tuning boxes, such as the one Larry is making.

Larry has illustrated his post with several excellent photographs, which should give you some idea of how to proceed if you want to design a similar system.

I can't wait until Larry has completed the tuning assembly and builds the magnetic loop for his station.
