Short Dipole Antenna
No, it is not a KGB antenna, even though it’s overall length makes it a stealthy antenna: 1m8 for the 40 m band! This antenna project is my implementation of the German “KGD” antenna: the “Kurz Geratener Dipol” (i.e., “the dipole that turned out short”). No, it is not a miracle antenna. But I am very pleased with its performance, and it definitely is an option for those with space restrictions.
The antenna was developed by a team of the DL-QRP-AG (Arbeitsgemeinschaft für QRP und Selbstbau im Amateurfunk). The manual (“Baumappe”, ref. 1) is available from QRPproject.Unfortunately, they no longer sell the antenna kits: center section with pre-wound coils, and pre-cut aluminum tubes. But: so what? Amateur radio is about building yourself! TheQRPproject website has an extensive forum [in German], where this antenna has been discussed (ref. 1).
