WebQuick SWR Calculator for Vertical and Dipole Ham Radio Antennas Here’s a really simple way of double checking how to much to trim your antenna elements. You only need to type in the numbers in the Cyan boxes. For … WebFeb 13, 2024 · High SWR means it doesn't leave the antenna, but bounces back to the radio (and bounces off the radio back to the antenna and back to the radio...and a little escapes at each end on each bounce). Low efficiency ironically can improve SWR, but it means that the energy is turned into heat instead of radiating out of the antenna.
High SWRs with Dipole WorldwideDX Radio Forum
WebThe SWR can be calculated by taking the ratio of the impedance to 50 ohms, giving SWR = 73/50 = 1.5. (By the way, for impedances less than 50 ohms, the SWR is calculated using … WebMaybe you can help solve my dipole antenna SWR issue 3,566 views Mar 21, 2024 I bought this antenna off the internet and have had a SWR of 3, at one point it tuned in perfectly however it is... shiro-spring 1.9.0

WebHigh SWR on 10m dipole I made a 10m dipole with 12AWG wire and a 1 to 1 balun to try and get on 10m FM. The antenna is about 3 meters from the ground almost horizontal. When I … WebJul 28, 2024 · The dipole still behaves the same way as far as sending signals out (the pattern of the radiation doesn’t change), but the feed-point impedance will have changed from about 72 Ohms to about 100 Ohms. Here’s the results from my modeling program: Feedpoint (1) – Z: (97.900 – i 1.103) WebSuper High SWR on homebrew 2m vertical dipole. Noob here, Technician license holder for maybe 4 days. I attempted, as my first homebrew antenna, to build a vertical dipole. I got my SWR meter, and at ~144MHz, I was getting an SWR of around 4.76, on ~148MHz, I was getting 4.95, and smack dab in the middle of the band, I was getting my lowest SWR ... shiro-spring 1.11.0
