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.
