Did you know?
WebJul 26, 2024 · Well, one answer is to simply check your VSWR by transmitting on a higher frequency, if your VSWR goes down, you need to lengthen your radiating element for the frequency you want a lower VSWR for, conversely, if you get a lower VSWR when … WebYour SWR is creeping up with power applied in longer transmissions like digital (FT8, RTTY, etc), Long SSB transmission, or CW high speed chatting. * The EFHW transformers …
WebThe term “SWR” means standing wave ratio. An “SWR” meter is used to measure how well the transmit power signal emitted from a transceiver (radio) is traveling through the antenna system into the atmosphere. Checking and setting the antenna SWR is critical to overall performance of transceiver (radio). During installation of a Business ... http://www.hamuniverse.com/swr.html
WebMay 4, 2024 · You can take a length of coaxial cable with a short circuit at the far end, and at the correct length your SWR will be one to one. About 18 feet of cable is the length for CB. http://www.hamuniverse.com/testingswr.html
WebSep 21, 2024 · At longer lengths it will project more resistance and more inductive reactance and close to 0.47 wavelengths it will be highly resistive and have neglible reactance as per the diagram below: -
WebJun 21, 2009 · Lengthening the whip lowers it on lower channels and shortening it makes it lower on he higher ones so with that in mind you know whether to make it longer or shorter, check it on the band edges and shoot for lowest the middle. biology wordleWebAug 14, 2024 · Aug 14, 2024. #7. Commercial radios, like the Motorola the OP was referring to, will do just fine with a higher SWR. Commercial radios have a high SWR monitoring circuit that will start reducing transmitted RF power if the SWR goes high to prevent any damage. You are correct on your length vs. resonate frequency statement. biology word for cWebAug 31, 2024 · 5. Simply fold the excessive lengths at the ends 180° back along the dipole and tape them to the antenna. It's that simple. See this post, where insulated wire was used.
