|RadioShack XMODS’ antenna wires are susceptible to being broken with frequent wrenching. The break is usually where the antenna wire coming from the receiver is soldered to the eyelet that’s connected to the piano-wire antenna extension. The wire is easy enough to solder back on, but you may have to do it over and over. To fix the problem permanently, carefully strip about 1/8 inch of insulation off the end of the wire, and then slide 1/4 inch of thin, heat-shrink tubing over the wire. After you?ve soldered the receiver wire back onto the eyelet, slide the heat-shrink tubing over the junction, and shrink it into place. The tubing will substantially reinforce the joint and help you avoid future antenna-wire problems.
