Stryker 955, tuned for low DK and swings to factory rated spec, it’s not all cranked up, aligned, and amp is typical custom 2 pill HD. Let me say, thanks for all the advice. It’s good to see people responding to my problem and offering to help trouble shoot. Warms my heart that there is still good people in the world. Ok, with that out of the way, let me give a quick run down... radio is new and works awesome. Amp is new and I’m hoping it’s fine as well. I’m hoping it’s actually an antenna issue. I only mention that because of the age of this antenna. I’ve been using it since 2012. It’s had some issues on this vehicle for quite some time with several different radios. Mainly unwanted noise. It’s always had low swr readings on a inline meter, and usually the radios built in meters are somewhat close to the inline. So with all that said, I ordered a new Sirio magnet base the other day which came with much more coax length then the original even though it had the same part number. Anyhow, it is RG58U cable. I know it’s not the best but it’s what it came with. Now...I vaguely remember trying to use a Killer Bee 250HD in this same vehicle, with another radio, and same antenna years ago and I had the same issue. It threw the radio into swr warning Magnum S9 at the time. I also tried that same Tx Star 250HD with a CRE8900. Same antenna, same vehicle, same results. Evidently I’m a slow learner but maybe my antenna is failing other then the magnet? Everything that has been mentioned about coax length, and tuning in the previous post, I can understand that. Makes sense. I just can’t get over a few diff rigs and boxes in same truck with same antenna with same results. Call me dumb now thanks y’all. Keep em coming!
