This was because the ground plane wasn't well established. Just because you have DC continuity doesn't mean you have a good RF ground. This is another reason CB antennas are difficult because of the amount of required ground plane to get the antenna to function properly.
Ahhhh, but this is where 1/2 wave antennas come in real handy....though it's a wee bit impractical at 27MHz
