My center lead is HORIZONTAL (attached to the ceiling) and the shield is Vertical and I get a 1.2:1 match. Keep in mind that this in my basement because I live in a Condo, no antennas allowed outside. I can get out around 4 to 5 miles running a Galaxy DX959 and D104 M6B Mic powered by a Pyramid 12 amp power supply. What more can you ask for.
I got a 959 in my truck. Good little radio. Sounds great and gets out far.

Always tune the antenna for lowest SWR. The better the match, the happier the transmitter/amplifier. I suspece you could have a component in your antenna that isn't handling the extra power well, or have a grond issue.
