FM Tuner Antenna Question


Then I insert the male "F" connector into the tuner's female connector and tighten it, a couple of of stations seem to distort and crackle. When I unscrew the threaded portion (I assume the ground) and just leave the center solid core wire connected, the noise and distortion disappears. Any reason why this should happen. I am using a FanFare FM-2G, 1/2 wave whip antenna inside a condo. I am in a suburban area, only a few miles from the antenna. I have planty of signal strength on all FM stations. This only happens with two stations. Any ideas why?

Is the center copper wire on your antenna wire (input) sticking out past the connector end too far? This can cause problems. It should not protrude past the connector hosel. If it is, just clip off the offending length of copper antenna feed so that it is flush with the hosel surface. (Approximately 1/4 inch of bare copper wire will be exposed in total). I hope this information helps you.
What I mean to say is that the center copper conductor, if protruding TOO FAR, might make for unintentional contact with other metallic objects in your tuner chassis. The receptical is designed for about 1/4 inch of copper for its intended antenna connection. By loosening your connection you may be relieving the extra length of unintentional "short circuiting" but not making the necessary ground connection. In short, If the copper conductior is too long, try trimming it. You have nothing to lose, as the termination is easily remade.
