Rex, It could be a 2 element parasitic array for 20 meters - where it is a little shorter than a half wave, but the reflector or director would have to be resonant on the band of operation. A wire of that length would work with a low radiation angle on 15 meters, but the lobes will be at a higher angle on 10 meters where it is approaching a full wavelength.
One thing you could do is space 2 of them a ways apart (about 16 feet) and feed both of them with the same length feedline. That will give you a directional pattern that is perpendicular to the plane of the elements (broadside array is a term typically used). Yes, that video is woefully uninformative, all that was accomplished was to demonstrate that the K2 tuner could tune it - note that the K2 tuner has a very wide range. 73, Don W3FPR On 5/8/2012 4:14 PM, Rex Lint wrote: > I don’t quite get their claim: "The SWR is 1:1". > > They are using a tuner, so the question is, what is the SWR on the ANTENNA > side of the tuner, not what does the K3 says with the tuner on... > > Now, can you make 2 of these and place them at a strategic distance between > them, making the other one a little longer for a 2 element parasitic array? > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
