electrical extension cord into an effective HF antenna for his Airspy HF+ SDR. The scrap wire is combined with a US$15 NooElec 9:1 balun which helps improve the impedance match of the antenna. He then stretches the dipole out through his backyard and then hooks it up to his Airspy HF+...
The HF Broadband Two Element Folded Dipole Antenna provides optimum performance over complete HF band, eliminating the requirement of multiple antennae or an Antenna Tuning Unit (ATU). Design & Construction: The antenna is designed by using two folded arms with a matching Balun. Installation: It ...
As the antenna is balanced, i.e. neither side linked to ground, it is necessary to use either balanced feeder, or if an unbalanced feeder such as coaxial cable is used, then a balun - a balanced to unbalanced transformer should be used. The radiation pattern of the basic half wave ...
itself, distorting the radiation pattern and changing the impedance seen by the line. The dipole can be properly fed, and retain its expected characteristics, by using abalunin between the coaxial feedline and the antenna terminals. Connection of coax to a dipole antenna using a balun is plot...
