Here is what I just got, Cobra 29 LTD Classic that was bumped up a bit, a new
Palomar Elite 300 amp (ebay) , Diesel (?) noise canceling mic and a Wilsom 5000 mag mount ant. Most "tune-ups" involve stretching the coils that make up the low-pass filter. A watt meter reads all wattage, no matter what it's frequency. Now your amp and antenna reject the second harmonic and reflect it back to the radio. I cant get the SWR down below 2.5. I ran a new 18' cable and a ground wire to the frame of the truck but ever time i key up the ANT light lights up on the radio. My questions a 1. How can I get the SWR down? 2. Is this a good combo? 3. on my amp it has a ON/OFF , HIGH, MED, LOW and a PRE-AMP on and off. What is with the PRE- AMP. What you failed to mention was the SWR with the amp out of line. -Scott, with the KW-7 really mounted to the rear bumper, and a 1.5:1 SWR that TALKS. I still prefer resonance to perfect SWR! Oh yeah, 7 feet of coax...enough to make it from the box to the antenna mount. No crimped connectors here. 2x455 box fed by #6. |
