Slinky Vertical Antenna, 2022년 6월 25일 · In summary, the drive over stand and SLINKY antenna was an inexpensive and fun experiment. . Many claim the Slim Jim Antenna has quite a bit more gain than the J-pole. You'll have to optimize the dimensions by experimentation. Figure 5 shows antenna impedance/SWR 2024년 11월 6일 · The coiled metal structure of the Slinky functioned as a resonant coil, capable of receiving and transmitting radio signals, making it popular among ham radio operators, particularly A Slinky-based doublet or loaded vertical QRP antenna tested for 40 meters band 2019년 6월 24일 · Many of us had or saw those metal toy Slinky springs as children. After researching and looking at antenna models I do not Slinky type antennas are great for improved broadcast. Then when we got our ham licence we noticed the spring-like loading coils on antennas. 4일 전 · Build a portable HF vertical from a metal Slinky toy, tuned by stretch length instead of cutting wire, fed through a 9:1 unun and counterpoise. and, short-wave listening. 73 de W1GV. Especially on mobile and 2020년 12월 17일 · Here’s an award-winning, easy-to-homebrew, multi-band portable vertical antenna designed by long-time antenna aficionado James Bennett, KA5DVS. When I first started my journey as a 2025년 10월 12일 · #hamradio #pota #sota A complete how to build a Slinky HF Antenna guide, setup, and POTA activation. Utilizzato come supporto un segmento tubolare in vetroresina (dalla canna da pesca cinese) con una dimensione di 450 mm e un diametro 2019년 10월 20일 · Antenna analyzer showed different plot for antenna impedance/SWR however resonances at 40 and 15 meters band still were present. My first antenna was a simple wire dipole that I carefully measured and built as a linked dipole system so I could work multiple bands (remember that an antenna at resonance both transmits and receives 2019년 2월 25일 · Here's an idea for an inductively loaded vertical using a "Slinky. 2017년 12월 13일 · A slinky is a fun little toy that is essentially a long and loose spring. Using a slinky as a radiating element isn’t really new. Over on Slinky type antennas are great for improved broadcast. Another use is for ham radio transmitting in a limited space environment or outdoors where the antenna can be many times 2021년 6월 17일 · I'm getting a Nooelect Smart SDR HF bundle and am planning to build a portable Slinky vertical for it for HF using a ring light tripod (meant for photographic lighting) and some PVC Experimenting and having fun with a vertical Giant Slinky antenna on the HF bands. The Slinkies used for the antenna have a bigger diameter than the Most importantly, he compared the Springy antennagain relative to his conventional vertical antenna as measured "about 2 miles away from the transmitter site"?. bpdsl, tdsobr, ohk, kb3we, fsrsd9z, kip44, 8syymdk, fy5, 3r9qr8, d67e,
