Make the wire ends about 10 mm longer than calculated, and tune the antenna by cutting a couple of mm at a time. Constructionįrom the main view you can select “view end detail” and “view center detail”. This will give you the dimensions for your driven element. Then select “meter/cm” or “feet/inches” as you desire. This determines the velocity factor for the calculation. Input a frequency (choose a centre frequency for your desired band), and the type of coax you will be using. When you run the program, you will see the main view as shown below: The program I used is called Coaxdipole.exe © Al Legary VE3SQB
So far I have made the following versions: I’ve taken the project a few steps further, and mounted the elements in electrical conduit. As stated in the application, the design is reasonably wideband (a trick here, make the element from RG-8 / 213 for wider bandwidth). It’s ready to run.Īll the basic construction details are included, and you can design an antenna for any frequency.

Go to and look for the icon labelled "Coaxial Dipole", and download to a suitable sub-directory on your PC. You may want to check his commercially made “Wave” antenna at

Al has given permission for free distribution of his coax dipole application. There are some other great antenna projects as well. Here is an application I found at This is the webpage of Al Legary, VE3SQB. Awkward you say? I would agree! What if I told you can make a 50 ohm version directly from RG-58 or RG-8 / RG-213 cable? The above versions need some sort of matching to enable use at 50 ohms. This Blog is mainly dedicated to Amateur Radio (Ham radio) and contains external articles and personal esperiences.Many would be familiar with the traditional folded dipole made from tubing or wire, and possibly the lightweight version made from 300 ohm ribbon cable.

IT System Engineer, recently started having fun with morse code and Raspberry Pi Licensed Amateur Radio operator in 1996 as IW5EDI, active member of ARI Firenze and ARRLĬlass 1970, married with two childrens, love experimenting and antenna home-brewing. The ICNIRPcalc is a MS windows application of aprox 900Kb, I’ve tested under Windows XP (running on a virtual machine under my MacOS) and is Multilingual too, having an English German and French translated interface.

You can directly downoload the software from here or by visiting the IARU Page where the software is hosted under the EMC section. I’ve enjoyed playing with varing Output Power, coax cable and band and noticing the changes in EIRP or Ant. The software is free to use, and is based on a german version, that is much older but suited for German antenna safety regulation, that looks like to be very strict. You can choose by many popular antennas, and I found even my GAP Titan DX antenna… but if you cant find it, you can always create your own antenna, from the File Menu you can choose “Construct your own antenna” and you will be able to put your custom values. DL9KCE released a new version of his ICNIRPcalc software that allows you to calculate safety distances for many know amateur radio antennas with respect to ICNIRP limits.Ĭalculations are done by considering many depending factors, like your Antenna characteristics, Band, Gain, Power Output, Coax Line, additional attenuation and many more.īy variating any of these values a different Safety Distance is calculated.
