Do you need a digital SWR meter, or is an analog OK ?Bad, this is ”water under the bridge” advice; however, you should have checked your old setup with a SWR meter before replacement. The old equipment may have been satisfactory. I purchase a SWR meter 10 years ago for approximately $20 on Amazon/Ebay when working on my rig. As @Don S/V ILLusion advised, you’re really going to have to check your rig with a SWR meter to determine if there are problems with the cable, antenna, & connectors.
