The Dish is 1. If op’s antenna is only a single piece of wire (I can’t tell), then something else on the device, likely the ground plane on the pcb, will be the second element. The basics and types of antennas include horn antenna,parabolic antenna,helical antenna,slot antenna,dielectric antenna,patch antenna,phased array antenna,dipole antenna,directional antenna,folded dipole antenna,ground plane antenna,YAGI antenna,Log periodic antenna etc. Remember that an antenna is also your first filter/preselector! After several years of contesting the 20m band appears one of our most successful bands, with the 5/8 wave vertical antenna being a crucial part of this success. Well, not just the television antenna – also a 160m helical vertical, a VHF/UHF discone antenna and a sloper for RX only. The helix is a relatively broadband antenna and small dimensional irregularities have little effect on performance. Shop in from Moonraker UK Ltd. By order 1240 - 1310 MHz. 4301305 62. The half-wave dipole antenna is discussed. National Health Act 1953. 5 cage concorde parallel 20288. used for a 23 cm DL6WU Yagi built on a boom made from 1⁄2 inch outside diameter (OD) aluminum tubing with 0. GL Mike K9QHO AMSAT 33589 > > Spring is coming --- and I have gathered almost everything for an L Band > uplink. However since then I made several successful tests so. Fortunately a group of antennas collectively known as helical or helix antennas exist which are both easy to manufacture and adjust, having very broad bandwidth and.
