Hello experts!
I am new to GMRS and having some issues with tuning my SWR on the Radioddity DB25-G radio and Rugged Radios UHF Stealth antenna on a 1997 Jeep Wrangler. I have the antenna mounted on the cowl by the driver door using the Rugged Radio mount. I ran the coax into the windshield channel, drilled into the frame to route the coax up by the rear view mirror. Currently getting a SWR of 5.8 using a new Surecom SW-33 VSWR meter. Tested ground on antenna mount to battery negative and saw .5 ohms. Also tested from ground connection on PL-259 at the radio and got the same reading. I do not have another antenna to swap out at the moment.
Also as a reference point, I also have a Radioddity GM-30 HT. I put the SW-33 between the radio and the factory antenna to get a baseline. SWR was 3.6 for this configuration. Using GMRS channel 16 for all tests.
Any help would be greatly appreciated!
