I ran across this fascinating article by Don Keith (N4KC) while I was searching for some new antenna ideas.  In this article, Don discusses five basic, easily-made antennas that will get you on the air quickly with a decent signal suitable for both DX and casual contacts.  According to Don, these simple, effective antennas are easy to build and use readily available materials.

Here are the top five get-on-the-air-quickly antennas:

The half-wave wire dipole.
The doublet with parallel feed lines.
The quarter-wavelength vertical with ground radial system.
The horizontal loop.
The original G5RV (a great antenna for the 40 and 20 meter bands).

Don does an excellent job of describing the theory, design, construction, and…

If you need an emergency 2 meter, 1/2 wavelength antenna for your next portable operation, look no further than a piece of unused coaxial cable in your "junkbox." In this video from Aaron of "Prepping Ohio", we see how easy it is to convert some surplus cable into a simple, effective, and light weight antenna for 2 meters.  Add this antenna to your "Go-Kit" today.

N7EAA's 65 foot vertical for 160M. Post #1255.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=LXcInIk1fGo.

Here's a dual band top loaded vertical antenna that covers both the 160 meter and 80 meter amateur radio bands.  For this project, N7EAA used a MFJ pipe for $200, galvanized steel electrical fence wire, and inexpensive poly rope for guy supports.  You'll probably need some help assembling and erecting this antenna. Like all vertical antennas, you will need a good ground radial or counterpoise system.  In this video, N7EAA attaches his ground system to an aluminum plate at ground level.

Homebrew antenna , 10-40 meter loop antenna. Post #1253.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=3T1LOGahiwY.

Here's another HF loop antenna idea if you have some trees or tall supports in your backyard.  Marcus Schrader built this full-wavelength 40 meter loop (143 feet/43.59 meters) and suspended it 20 feet/6.09 meters above ground using a few trees in his back yard.  He uses a 4:1 balun along with a length of 450 ohm ladder line to feed the antenna.  Marcus uses this combination with an antenna "tuner" to cover 10 through 40 meters.  As you can see from the video, the antenna is fairly "stealthy".

Comment:

Now that the FCC has established rules and regulations for the 630 and 2200 meter amateur radio bands, radio amateurs can now expand their contacts with frequencies below the standard broadcast band.

One of the prime concerns related to these bands, besides running low power and non-interference for existing services, is the type of antenna suitable for such low frequencies.

It's possible to design a relatively small vertical monopole antenna that will perform well in the rf "basement", thanks to this antenna simulator for 472 kHz.

Although this simple calculator isn't a replacement for software such as EZNEC, it will give you an indication on how this type of antenna will perform.  Just plug in the raw data about antenna type, antenna dimensions, and estimated gro…

If you have a few old CB antennas around your shack, why not covert some of them into 10 meter mobile or home station use?  My current 10 meter vertical antenna is a cut down 108-inch/274.32 cm steel CB whip I bought years ago at Radio Shack.  Used as a ground plane antenna, this converted CB antenna does a good job on 10 meters when the band opens.

In this video by Tony (KD8RTT) and his brother Andy (KK4LWR), we see a simple way of modifying a CB whip antenna for use on the 10 meter Amateur Radio Band.  Their MFJ HF/VHF SWR analyzer helps in the trimming process.

Don't let that old CB antenna go to waste.  Convert it now into a simple, effective mobile or portable antenna.

Antennas in the Attic: Ham Nation 215. Post #1239.

This excellent video with Gordon West (WB6NOA) comes from the Ham Nation program, episode 215.  In this video, Gordon shows how radio amateurs remain active by placing a variety of antennas in their attics.  Sometimes, there are no other alternatives because of deed-restricted housing (HOAs and CC&Rs). A few of these compromise antennas work quite well, delivering hours of operating time to antenna-limited areas.  Hopefully, some of these suggestions will help you get and stay on the air.

Build your own 110 foot multi band dipole home brew ham radio HF antenna. Post #1238.

. If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=5B0wCP2Tsdw.

Here's a simple, efficient, and inexpensive HF dipole antenna that covers 80 meters to 6 meters.  The key to multiband operation is the use of 300 ohm twin lead as a feeder and a 1:1 ATU balun.  You can also use 450 ohm ladder line or home made balanced line into a 1:4 current balun and then connecting the antenna feed line and balun to an antenna "tuner" with a short length of 50 ohm coaxial cable.  W5XJ provides a list of easily obtainable materials for this versatile antenna.  If you have only one tall support, you can configure the antenna as a dipole "sloper" antenna.

CB antenna to ham radio. Post #1237.

If you can't view this video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=oYg9jbdjTIw.

Excellent, well-paced video from "Musings" showing us one way to convert a 5/8 wave CB antenna for ham radio use.  Depending on your interests, this video can help you transform an old 11 meter (CB) antenna into an effective vertical antenna for 20, 15, or 10 meters with just a few shop tools and a little imagination. I've converted a few 108-inch/274.32 cm CB whip antennas (from Radio Shack) into usable 10 meter vertical antennas without much difficulty. While this video has a bit of a learning curve, it shouldn't be too hard to copy the procedures shown and build your own, inexpensive HF vertical antenna from unused or discarded CB antennas.
