Daermos Posted October 25, 2017 Author Report Share Posted October 25, 2017 Daermos have you tried cleaning the carbon-rubber contacts with soap and water and a tooth brush?Ron I used rubbing alcohol to clean them with no luck Sent from my LG-H900 using Tapatalk Quote Link to comment Share on other sites More sharing options...
ron350 Posted October 25, 2017 Report Share Posted October 25, 2017 I only clean the rubber pads with soap and an old soft tooth brush then clean the copper trace contacts with alcohol. Once the rubber pads no longer conduct they cant be repaired because nothing will stick to them. Quote Link to comment Share on other sites More sharing options...

Grandprix1 Posted October 25, 2017 Report Share Posted October 25, 2017 I believe the antenna is that strip on the top of the back side. If you can get me a measurement of it i can tell you if it is or not. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
98gpgt Posted October 25, 2017 Report Share Posted October 25, 2017 I don’t suggest altering the antenna unless you know exactly what frequency it uses and can figure out how long it needs to be to be resonate. Otherwise you run the risk of burning up the transmitter. So the receiver part of the transmitter is what could be damaged. I understand the concept of impedance matching, but AM/FM radios have extendable antennas. So do older cell phones. Isn't extending an antenna in effect like moving closer to the companion transmitter? Quote Link to comment Share on other sites More sharing options...
jimmyfloyd Posted October 25, 2017 Report Share Posted October 25, 2017 I think reception problems are usually a result of the unit in the car having issue, rather than the fob. The fob is usually the contacts on the button, or the battery clip coming unsoldered. Quote Link to comment Share on other sites More sharing options...

You would receive better if you had a 1/2 wave length or larger. I’m pretty certain it’s in the 800mhz range with cell phones. 468/800mhz is about a half a foot for a half wave antenna. If it’s down in the 430mhz it should be about a 1ft long. It’s a compromised antenna which hurts TX a good bit. Quote Link to comment Share on other sites More sharing options...
