Well, I finally got around to fitting the new SteppIR 30/40M Kit to my original 2 element SteppIR.
The 30/40M Dipole is simply a driven element which functions as a Dipole from 6.8Mhz to 13.8Mhz and it also acts as the driven element for the main Yagi between 13.8Mhz tand 54.0Mhz.
A normal Dipole for 40M would be approx. 64 feet long whereas this element is 39 feet long, created by looping the element tip back towards the boom. On 30M since the copper tape barely turns the corner back towards the boom, essentially it performs like a full size dipole would.
More information on the SteppIR range of antennas can be found on the website of Vine Antennas. Further reading and images on how I constructed this & other SteppIR products can be found in the Gallery and also under the Radio Projects page on this website (in the coming days.) Thanks to Ron Stone GW3YDX (Vine Antennas) and John Muzyka G4RCG for their help and advice with the 30/40 Kit.
