Here are some links for antennas and I will be adding more, there is a bunch of information in these links.

The Moxon Antenna Project is located at the following link.  If you scroll down there are many configurations for the small compact beam that all work well.  From my own experience this beam will work great even non-free space.  I played with my 10m versions at 10' for a very long time and it worked great.  It did identical signals at 20' and came up about 1/2-1 s-unit at 30'.  That's part of why I want to build one.  The F/B ratio is fabulous...or rather has been on the 10m versions I've made.


There is a free download program on the site that will give you complete measurements.  I've found it to be very accurate except on vertical.  I made a vertical version as well that was a little off.  But very close.  It's a great little beam and very easy to make.

HF antenna

HF Antennas
The simpliest antenna for getting on HF and working DX is the dipole antenna. It can be fed with coax line, and the antenna can be placed just about anywhere in any configuration. Ideally the antenna is high enough to be at least one-half wave length above the ground. For 20m, that is about 33 feet.

Choose any wire you wish, between 18 and 14 AWG. Stranded is easier to work with, more flexible and less likely to kink (and break at the worst time).

At the center of your dipole, use a 1:1 CURRENT Balun. (Radio Works makes and sells good baluns).

Feed your antenna with RG8-X to your radio station.

The general formula given for the overall length of a dipole based on frequency is L = 492 / f(Mhz)

Where L is in feet, and f is in Mhz.

L = 492 / 14.2 for the phone portion of 20m band.

Add 5% to the length if you use insulated wire.

L2 = 1.05 * L

The "nulls" of the dipole are in the direction of the wire on each side of the feed point. The nulls are reduced and eliminated if the dipole becomes an inverted-V (when the center feed point is raised so high that the antenna resembles an upside-down V.)

When the dipole is mostly horizontal, then the radiation pattern has distinct nulls off the ends of the wire in the direction of the wire.

Home Brew Antennas


Over the last 40 years G5RV dipoles have become the most widely used general purpose multi-band antennas in the world. Good performance, modest size, low cost, simplicity, and versatility are the reasons for this popularity.
    Invented in 1946 by Louis Varney, whose call sign is G5RV, the basic antenna measures only 102 feet across the top, and is fed at the center through a low loss 30-ft feed-stub. The interaction between the radiating section and the feed-stub makes the G5RV easy to match on all-bands from 80 through 10 meters with an ordinary low-cost antenna tuner. In spite of small size, it provides dipole equivalent coverage on 80 and 40 meters. From 20 on it favors DX with four to six low angle lobes reaching out in all directions.

    Want Complete Data? Get Technote 124 from Antennas & More. With 36 pages on the G5RV, it's the only complete reference. The Technote explains why the G5RV works, shows radiation patterns for each band, details the effect of height and configuration, answers commonly asked installation questions, gives step-by-step instructions for assembly using commonly available material.
     Antennas & More provides three types of G5RV antenna system in sizes to fit every need and situation.  All use rugged kink-proof insulated wire and are rated for full 2KW legal power.

Antennas & More G5RV
     Designed originally for use by an international rescue and relief organization, this family of G5RV antennas is made of the most durable and easily used materials available. Fully assembled and ready to go, it is the fastest way to get on the air.
    Our insulated wire top section rejects kinks and protects against corrosion and accident. Special feed-stub material resists abrasion and refuses to work harden and break when whipped in the wind or repeatedly deployed and rolled up for storage. Sleek non-reflective black design makes this the least obtrusive G5RV on the market. That's why this is the most popular G5RV for rooftop and attic installation. Completely assembled and ready to hang up, with a PL259 on the feed-stub to connect to your coax, and we also included a barrel connector.

Requires antenna tuner.


fan dipole

Fan Dipole -- How Long to Make Them

 Here are  the dipole measurements.  Print these and save them. You can add as many of these as you would like to a single coax point and make a fan dipole or what's called a multiple band dipole.

(Each leg is shown in length so you will need two legs.)

10 METERS = 8'4"
12 METERS = 9'5"
15 METERS = 11'1"
17 METERS = 12'10"
20 METERS = 16'8"
30 METERS = 23'2"
40 METERS = 32'9"
60 METERS = 43'7"
75 METERS = 60'9"
80 METERS = 65'6"
160 METERS = 123'5"
137 KHZ = 1708'1"

Here are some links:


 These dipoles will work either by themselves or as a fan dipole when constructed properly. Please refer to the links for proper building of them.

My Skywire Loop Antenna

by Don Keith, N4KC

First, let me reassure you that such an antenna does not necessarily take much room. One reason I went to one in the first place is because I didn't have room for a 260-foot-long dipole for 160 and I wanted to give the "top band" a try for the first time in my 45 years of being a ham. If you are talking 75 meters (and up if you want a multi-band antenna...more later on that), it's only about 65 feet on a side in a square arrangement. Yes, it could be a lightning attractor, but you should take precautions with any antennas, including this one. And, as noted, the skywire loop can be a fine, fine multi-band antenna that actually has impressive gain as you make it bigger or use it on higher and higher frequencies.

Okay, let's build one! CONSTRUCTION NOTES........ for the rest of this follow this link
