Response to the article of DJ5IL via short antennas. I'm fed up to the back teeth to respond to the taunts of the so-called "RF experts", I must defend me against some statements from DJ5IL that directly attack me. To the one I take not the unit of Landstorfer and Meinke as my antennas, but mention the two physicists as viewer of new knowledge of small antennas produced RF field. I have purely mathematically considered for the first time the capacitive antennas, measurements created, led several QSO's in comparison to my dipoles and analyse the results, created a new equivalent circuit of the antenna and thereby developed completely new formulas and programs for the calculation of the capacity and the total antenna. I use new power tracking locks, which are no longer heat up and thus free of any loss in the district involved. I spread my knowledge free of charge to all other ago / and followers, of which I myself decided would like to dissociate. To the 2., I have never claimed that no radio frequency fields are on the coaxial cable. These are negligible at the antenna and hardly detectable at very good coupling from the ground on the coaxial but compared to the RF fields. The RF fields on the Koaxleitung are not relevant for communication. These RF fields disturb not the radio and television operations - also no direct radiation. The coaxial cable is in addition to the devices. The reduction factor of Koaxkabels of 0.66 is well chosen. At longer or shorter lengths a SWR of 1: 1 in the resonace case is not accessible. The antennas are mere steep field producers through its low construction height. The antenna is operated out of phase, is the current to the tension almost 90 degrees at the entrance of the coil. Thus, no magnetic pulse as in a GP, which radiates in the feed point is created. The coil is not as good as warm. Only the resistive part of the wire is here for heating. Blind shares have been eliminated, because there is resonance. These antennas are with...NC, MM ANA and other simulation programs not representable! Of furthermore the coaxial cable in the ground can be buried without compromising the quality of the antenna including. Amateurs from the States have reported to me that the small antenna at 2 meters height to an essential is calmer and more effective than a comparison dipole and ranges were achieved, which are simply amazing. The coax cable was under 1 meter snow! Note the frequency fields of coaxcable here.... hi hi. To read on my forum under "reports". A group with DL2ABC builds this tiny for 160 Meterband and are excited! Some of OM's of the QRSS group used since new these antennas for DX with milliwatt power. Let's not by this "HF experts" adversity you the fun of these small antennas, try it out, simply sets the cable into the car or carve it underground. Stir these dismissed with "God and the world", without an antenna, so times to build... I wonder just what that means? It would be better if these so-called specialists would contribute what positive one for the radio amateurs times, because this almost free, tiniest antenna for the shortwave is for some of OM's to be the only way of QRV. And here are some articles in German to read from the internet: http://www.qrpforum.de/index.php?page=Thread & threadID = 2467 http://CQ-CQ.EU/MV.htm#Deutsch http://www.qrpforum.de/index.php?page=Thread & postID = 17782 http://www.qrrr.ch/images/EMVG_Entwurf-Brief-Karl_Fischer_DJ5IL.PDF http://www.agz-EV.de/hamradio2day/Ausgaben/2007_270.html and much more... simply Googling...
