Do you need a reliable, sturdy, and inexpensive antenna for local or regional communications?  If you do, a simple NVIS (near vertical incident skywave) HF antenna may be what you're looking for.  These high-angle radiators provide consistent coverage out to approximately 500 miles/810 kilometers, depending on propagation and weather conditions.  I've used a simple 40 meter NVIS antenna mounted 16 feet/4.87 meters above ground level to check in to the Hawaii Interisland Net. My signal reports vary from 57 to 59.

In this post, Stacy (KH6OWL) provides a simple tutorial on getting started in NVIS communications. He provides drawings, photos, and three outstanding videos to explain the theory and oper…

New 160 meter antenna and launcher. Post #1616.

Besides the large size of most 160 meter antennas, getting the antenna high enough for a good take off angle presents special challenges. Most antenna references recommend getting dipoles at least 1/2 wavelength above ground to work decent dx--something that is often difficult to achieve if you don't have tall supports such as trees on your property.  Even if you have trees to support your antenna, getting the antenna launched into the upper branches can be quite a headache.  In this video, Dave and his friends solve that issue with a specially designed "pneumatic weight launcher" that puts antenna elements in a tree's upper branches without much stress.  I rather like Dave's design, having tried slingshots, casting rods, and bows/arrows with varying success.

If you cant's view the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=RkNSFmkNSk8.

Operating from a deed-restricted home, apartment, or condominium can be a genuine challenge.  Out-door antennas often perform better than the wires designed for indoor or limited spaces.  Alternatives to outdoor dipoles, verticals, and yagi beams can be found with magnetic loop antennas, indoor loops, and even mobile antennas adapted for indoor use.

Such is the case in this post by Mark Etzey, who uses the popular Yaesu ATAS 120A mobile antenna for his small apartment.  If you carefully adjust the antenna and use an indoor counterpoise system, you can get on the air with a usable signal.  Mark offers several helpful suggestions for radio amateurs who want to use a HF mobile antenna for their home station.

The Double Bazooka Antenna-A Review. Post #1611.

Image
If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=9xfpcD6xuSo

Rob (VK3BVW) does an excellent job of explaining the theory, design, construction, and use of  the double bazooka antenna.  This review examines double bazooka antennas designed for the 80 and 40 meter amateur radio bands.

If you're looking for an efficient, quiet, single band dipole antenna, you may want to consider the double bazooka antennas examined by Rob in this video.  A double bazooka antenna doesn't require the use of a balun.  The antenna consists of 50 ohm coaxial cable (such as RG-58) with the shield split at the center and the feedline attached to the open ends.  The braided copper shield of the coax is the actual RF radiator, while the center conductor acts as a matching transformer to provide a DC ground.

Try a double bazooka antenna for your favorite HF band and see what happens.  Experimenting with antennas is half the fun of…

Attic Mounted HF Loop Antenna in HOA, Does It Work? Post #1610.

Image
If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=cYd0l-PEPR8.

Here's another idea for getting on the air in deed-restricted housing (HOA/CC&Rs). In this video, Eric of "HamRadioConcepts" mounts a popular MFJ magnetic loop HF antenna in a friend's HOA-controlled home.  An inexpensive TV rotator provides some directivity for the antenna. While this attic antenna is not an ideal arrangement, it will get you on the air.  Another case of "out of sight, out of mind."  It's also possible to erect an outdoor stealth antenna, but that will take more care and planning.  But for now, try this magnetic loop idea from Eric. Digital modes should work quite well with low-power antennas such as the MFJ loop.

Comment:

Here's a handy calculator for radio amateurs who build their own antennas.  Dipoles and Inverted Vees are simple, basic antennas that work well if you design them correctly.  This article explains the theory and simple math equations that will give you the proper element lengths for these antennas.

Of course, your final design will be affected by several factors:

As you may already know, no two antenna installations are alike or identical in many ways, even when using identical antennas and each the same height above ground. The surroundings, height above ground, the ground conductivity, and many other factors can detune most any antenna. Even the length, diameter of wire used, and type of feedline can be a factor to some extent. Using larger conductor diameters for the antenna l…

A nicely done video tutorial from a 16-year-old newly licensed radio amateur who hopes his love for antennas will inspire us to experiment on our own and have some fun at the same time. "The Modern Adventurer" discusses dipoles and their variants, including the flat-top horizontal dipole, the inverted V, and the vertical dipole--all capable of delivering contacts with a minimum of materials and stress.

Dipoles are basic, simple antennas that most anyone can design, build, and use.  "The Modern Adventurer" does a fairly good job of explaining how these classic antennas work and how they can be modified to fit your operating environment.  I enjoyed the enthusiasm displayed in this video.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=AKoySzdKGIE.

Here's a simple magnetic loop antenna that can be built in just a few hours.  Kevin Loughin (KB9RLW) designed this antenna for indoor use during bad weather.  The only drawback for this antenna is the narrow bandwidth exhibited by the design.  Magnetic Loop antennas are stealthy, giving those living in deed-restricted homes and apartments an opportunity to operate without being noticed.  Magnetic Loop antennas also are ideal for portable and field operations.

A good, basic introduction to antenna gain from Stan Gibilisco (W1GV).  Stan discusses the theory behind all of those "gain" figures cited in antenna advertisements and promotions for radio amateurs.

Most of us radio amateurs are familiar with the standard Wikipedia definition of antenna gain "as the ratio of the power produced by the antenna from a far-field source on the antenna's beam axis to the power produced by a hypothetical lossless isotropic antenna, which equally sensitive to signals from all directions."  A nice, technically precise description suitable for exams and learned discussions of antenna patterns. But, in everyday terms, what does antenna gain mean?  Stan does a good job of illustrating antenna gain and directivity without resorting to complicated examples and higher level mathematics.  Of course, if you wa…

If you need a simple, efficient, cheap, and lightweight antenna for portable or field operations, the "HQD" Speaker Wire Antenna from Jerry (KG6HQD) may be the answer.  The antenna resembles several designs featured in past editions of the "ARRL Antenna Book."  Those examples used commonly available "zip cord" available at many hardware and home improvement outlets.  Jerry shows us how to build the antenna in a few simple steps.  Used with an antenna transmatch (i.e. "tuner"), the antenna is capable of multiband operation--something that should appeal to SOTA (Summits on the Air) and QRP (low power) enthusiasts. 

Based on research conducted by the ARRL and my own experience, these antennas provide excellent results on the lower HF bands (80/40 meters).  Higher HF bands may suffer significant losses, depending o…

Comment:  Have you ever wanted to have a strong, reliable, and fairly inexpensive antenna mast for your ham shack?  If you don't want to spend a lot of cash for such a project, Hank's (WV7U) Tilt-Over Mast may be what you're looking for.

According to Hank, the expenditure of around $300 US for locally available materials should provide all of the components needed for this sturdy mast. 

The most important part of the mast is the selection of the pipe needed to support your antenna:
"I used two different sizes of standard schedule 40 black iron plumbing pipe: 2" for the base and lower section, and 1-1/2" for the top section. This pipe comes in 21' lengths. Galvanized plumbing pipe of the same size would be OK too, but it was about 50% more expensive, and the zinc coating makes t…

Comment:

If you can only have one multiband HF on your property, then the W5GI Mystery Antenna may be what you need. 

John's W5GI antenna is a simple collinear array resembling the popular G5RV antenna, but with much more gain.  According to John, the "mystery antenna" exhibits about 6dB gain on 20 meters, with a 6 lobe pattern broadside to the antenna.  While the antenna is designed for the 20 meter amateur radio band, it can do very well on 160, 80, and 40 meters with the use of an antenna transmatch (i.e. "tuner").  Read some of the reviews in this post and see if the W5GI can work a "miracle" on  your property.

Comment:

If  your amateur radio station is confined to an apartment or a deed-restricted property, you know how difficult it can be to find a HF antenna that works in a severely confined area.  In this article by Simone (IW5EDI) he expands on an original idea from AC4DG and gives us a few antennas that could work in limited spaces.  Simone says you may have to try several designs before you find the antenna that works for you.  He offers a few suggestions worth trying:

A disguised outdoor wire antenna.
Multiband HF antenna on a vehicle with a long run of coaxial cable to your station.
Indoor wire antennas.
Cliffdweller II antenna (basically a slinky dipole).
Short, inductively-loaded vertical antennas.

I enjoy Kevin Loughin's (KB9RLW) videos because of their unpredictability, creativity, and just plain "craziness".  In this well-constructed video, Kevin takes his QRP station to an unused baseball field and converts the backstop fence to a HF reflector.  Strange as it seems, the idea works, and Kevin was able to make some solid contacts.  Great video!

A nicely  done video tutorial from Andy Wragg on how to build a NVIS antenna for local and regional coverage.  Andy uses a non-resonant design to build this dual band (40 meters and 80 meters) NVIS.  Because this NVIS design uses non-resonant elements, you will need an antenna transmatch (i.e. "tuner") to realize maximum efficiency and low SWR for this NVIS antenna.

Comment:

Fascinating, informative tutorial from Claude Jollet (VE2DPE) on how to build a linearly-loaded dipole which delivers full half-wave dipole performance with 30% to 35% less space than the classic dipole.  The radiation resistance of this antenna is about 30 ohms, so you'll need an antenna transmatch (i.e. "tuner") to get maximum efficiency out of this antenna.

Claude describes this antenna with excellent drawings, suggests helpful construction techniques, and explains the basic theory behind this shortened dipole antenna.  Claude also supplies a recommended antenna length for each HF Amateur Radio band. Check out this graphic to see how much space is saved through linear loading:

Here's another experimental antenna design from Kevin Loughin (KB9RLW).  Kevin says he got the idea from an article describing a military NVIS antenna.  Kevin states "I had the idea to rotate the design vertically and make a directional magnetic loop...it works surprisingly well for such a small antenna."  If you live in a deed-restricted home or apartment (HOAs/CC&Rs), this antenna may prove useful because of its small size and portability.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=QAW2KKWumcY.

I've always found the "tuning" process involved with small magnetic loop antennas to be somewhat tedious.  These antennas are very sensitive to small changes in frequency and adjustments can be a bit taxing. 

But, thanks to this excellent, informative video from Johnny of "Signal Search", the tuning process can become easier and less stressful.

In this video, Johnny uses a magnetic loop design by W4OP.  As with many magnetic loop antennas, adjustment of the coupling loop is vital to precise tuning.  With a little time and effort, small magnetic loop antennas can become viable options for those operating in deed-restricted homes or apartments.

Comment:

Although this antenna is a bit complicated, you may want to consider G4IZH's design if you can use no other antenna on your lot.  The "aerial" requires a bit of technical skill, but the rewards of completing this project far outweigh its challenges.

G4IZH says the antenna covers the 20, 17, 15, 12, and 10 meter Amateur Radio bands (14 MHz to 29.7 MHz) with a 1:1 SWR throughout the tuning range.  Each construction step is illustrated by excellent photographs and helpful suggestions.

Like any compromised antenna, there are limitations that should be considered:

Operating on 160 meters can be a difficult challenge for radio amateurs living in deed-restricted apartments and homes (HOAs/CC&Rs).  However, if you're willing to accept a few compromises in terms of height and orientation, you can still make contacts on the "Gentlemen's Band".  "Ham Prepper" has done just that with a meandering, stealth wire antenna attached to the back of his home and anchored to his property's privacy fence.  With the aid of a MFJ-989c antenna "tuner" and a simple ground radial system, this radio amateur was to make successful contacts on 160 meters.  This antenna is basically a NVIS (near vertical incident skywave) arrangement, which provides good local and regional coverage.  With the MFJ "tuner" and the 300 ohm feed line, this antenna has multiband HF capability.

Here's an antenna idea for radio amateurs living in deed-restricted apartments and homes.  According to Stan Gibilisco (W1GV), the attic of your home or apartment may have sufficient space to install a simple dipole antenna.  Depending on the type of roofing materials used in your home, an attic antenna may offer good performance while being totally invisible to prying neighbors. It's worth a try. Afterall, a compromise antenna is better than no antenna.
