20m Dipole Build

Tom has built a 20 meter dipole for portable use.The build is based on a common speaker wire dipole build. Using the HF Linked Dipole Antenna Designer from as a guide Tom set about building his. The parts list is very basic. length twin core speaker wire cut to size 1:1 50 Ohm balun with a SO-239 connector rated for 3 to 30 Mhz at 400 Watts. The intention is to deploy the dipole from a portable 6 meter telescopic mast with the legs supported by 2 to 3 meter long tent poles with 2 to 3 meters of rope extenders. Putting these numbers in to the designer application we get the following results. Using the commonly held belief that its easier to shorten the length rather then extend it after cutting, the speaker wire as cut to 5.05 meters. Next step was to test the SWR of dipole. Running a sweep over the 20m band gave the following results. We were very happy with that as a first attempt. Next steps will be to use this as a starting point for a linked dip

About The Club

Hi folks, The East Leinster Amateur Radio Club (EI0EL) is a brand new club founded just this August. We’re a group of friends interested in all things Amateur Radio, especially Portable and SOTA. I suppose we really got started over the Lockdown with regular group Zoom calls. During the Lockdown we spent a lot of time sharing home-brew projects and running classes in preparation for the HAREC exam, and I’m delighted to say we had two members passing and gaining their Amateur Licence this August. We are in the process of setting up a simple, no frills, website which we’ll build over time. So please don’t come here  expecting a lot of detail. We're spending our time getting out and operating rather than building websites. But we will put in some contact info and a brief Intro to the Club very soon. We are also in the process of getting our club contact details on the IRTS Club Info page. At the moment we’re all based in the Dublin / Kildare region and really looking forward
