A freeware dos program by John Agrelius released in early 90’s but still very actual. It allows to quickly calculate dimensions for Quads antennas, Yagi antenna, Inverted vees antennas as well as J-poles and Traps to extend dipoles band coverage. Just extract the antmaker.zip file and start the Menu.exe batch file.

Swiss Quad Antenna
Alain Miqueu, F6ITV Which monoband directional antenna can provide a good gain, a good F/B ratio, being not to large and mechanically within hamradio skill? As it is used to say, it’s a process that consists in searching the best compromise. This excludes high-gain and long-boom Yagi that are very large and heavy. A 3-element…
A Beginners’ Guide to Amateur Radio What is Amateur Radio? – Many Hobbies in One!
What is Amateur Radio, what do radio amateurs do? Do I have to buy expensive commercial equipment, or can I build my own? Will I need massive aerials (antennas)? What kind of licence do I need? How do I get one? Do I need to pass technical exams and morse tests? Where do I start?…
10 meter dipole
I was in need of an antenna for my 10 meter beacon, so I decided to build a design I remembered seeing in an issue of QST several years ago. A friend of mine built one at the time and it worked great. It is a simple rigid dipole made from two lengths of 1/2″…
YagiMax
Even if outdated, is still a good program to calculate and desing yagi antennas elements dimensions, sizing and spacing. I’ve used it to verify some antenna plans I’ve found on the net. It’s particularity is that you at first need to tell the program the size of your antenna and then, you can calculate resonating…
The flower pot antenna
About the project It’s a portable dual-band antenna working principally on 10 meters but also close to the 30 meter band. It’s compact, light, economical and doesn’t need any radial.If you would like to repeat my experiment you will first need a big plastic flower pot (around 70cm high, 60 top diameter and 30 cm…
How antenna traps work
Article by VE3GK I was assembling a HY/GAIN, TH6DXX, a 10 – 15 and 20 meter beam the other day and thought there might be some interest in the function of the traps. I have also included some practical information on howto build traps for a multi-band, 10-15-20 meter antenna. RESONATE PARALLEL NETWORKS REVIEWED: When…
K9FD Receiving Loop
RECEIVING ANTENNAS The K9FD Receiving Loop The Answer To Suburban DXing On the Low Bands – by K9FD Editor’s note: Merv Schweigert, K9FD, has been working jusl about everything on the 40, 80 and 160 meter band” this season. In this article he shares some of his experiences with receiving antennas. lf you live on…
Make a magnetic loop antenna for 7-21 MHz
This antenna has several advantages, not least being only 1 metre diameter! This loop relies on being horizontally polarised and receives only the magnetic wave, thus as most noise in the domestic environment is vertically polarised and electrical wave, it delivers low noise to your transeiver/receiver, which makes for nice clean listening. In addition any…
