After MUCH tinkering with antennas and coax FINALLY got swr down to about 4.0. Am now using RG-59 coax with 1/4 wave fiberglass antenna. Now where do I go? Assuming 4.0 is too high and need to get closer to 2.0.

You are sure you are running RG-59? RG-59 is 75 ohm coax, which is for TV use. CB and Ham radios use a 50 ohm coax. If you try and use 75 ohm coax in place of 50 ohm coax, it will generally cause this type of problem.

This took me back to 79/80, would here about a few people setting up mobile or home base with wrong coax, or even connect the cb to the car radio antenna , and 1 close friend of mine used a Hornby train set power supply it did not end well for him.
Hope he can get some local help to fix his coax.

I remember someone using a train set psu back then. Don't know if it did any damage but it had a bad buzz. Can't remember what i did yesterday but i can remember that 40+ years ago.

Car battery and a charger i started with and ran like that for a long time. Think the battery gave up in the end after being charged so many times plus topping it up with tap water lol. How things have changed over time and you can't even top up a battery anymore.

TV coax will work but you'll never get a SWR below 1.6:1 because of it.
What are you using for a RF ground? If you're using nothing then get four lengths of wire about 9ft long and attach them to the mount, laying them out in a cross pattern.
