Une vue des différentes sections de tube. A la base du plus gros diamètre, un cylindre de bois dans lequel est tourné un petit épaulement, ou deux cylindres de diamètres différents solidarisés par une tige filetée et des écrous.
The FLUTE ™ Antenna is a highly efficient, man portable, electromagnetic pulse protected, omni directional, high frequency (HF) radio antenna. With a significantly smaller footprint than comparable HF antennas, our patented FLUTE has extremely wide bandwidth.
In the near future I intend to do some tests with a random wire antenna which is 17.75m long. As the impedance of this type of antenna is about 450 ohm a 9 to 1 unun (unbalanced to unbalanced) is required to match with the 50 ohm output of the transceiver. The YouTube videos from TRX Bench (Peter) about baluns are very interesting.
Jul 29, 2020 · Its metal construction makes it heavier than other wall-mounted antennas and harder to hang. It comes with a 12-foot removable cable. The HD Frequency Cable Cutter Mini is the newer, smaller ...
Dec 31, 2018 · The MicroVert is based on a design developed by Jurgen Schafer (DL7PE). As built, the MicroVert is a short, base-loaded antenna that uses the coax shield as a counterpoise. While the Microvert doesn't perform as well as a dipole antenna, it can get you on the air where large antennas are not suitable or allowed.
Construction & Working of Micro strip Antennas Micro strip antenna consists of a very thin metallic strip placed on a ground plane with a di-electric material in-between. The radiating element and feed lines are placed by the process of photo-etching on the di-electric material.
Dual microwave antenna device used to generate and measure the spinwave (magnon) velocity and propagation distance in magnetic nanowires.
