"'Doc" wrote in message ... Patrick, Sorry, tuning the antenna 'off of' the car won't work (miracles do happen, but don't count on it). The most likely problem is as you thought, a not so good 'ground', but maybe not. Does anything you do change the tuning of the antenna at all? Maybe not get it to where you want it (freq.), but does change it's resonant freq? If not, then there's something else 'going on' besides the inadequate grounding/counterpoise. Make sure you have a good connection through the mount, no shorts/opens except as they should be, etc. And you probably should do something about the grounding/counterpoise, maybe clip a wire to the base of the mount as a counterpoise to see what difference it makes (just lay it on the surface of the car for now). The length of the counterpoise isn't that critical, but too long is 'better' than too short. Changing the location of the mount is also something you might try. Good luck... 'Doc |
