FloridaMan Posted February 28, 2019 Report Posted February 28, 2019 My GNS430W is experiencing reduced radio reception in the lower frequencies especially. At 119.65, I’m also picking up weather that I believe is broadcast in the 161.5 area. As part of the engine monitor install, I had the Loran, ADF and associated antennas removed so I believe it could be related to that, or maybe it’s this antenna. If anyone has experienced this exact behavior and knows the cause, let me know so in case the avionics guys don’t, it could be a starting place for them Quote
carusoam Posted March 1, 2019 Report Posted March 1, 2019 That sure does look like it could be the problem.... disconnect it... see if it gets worse... reconnect it... See if it gets better... Clean the connections, While you are there... See if @Alan Fox has a better one on a shelf... Best regards, -a- Quote
larryb Posted March 1, 2019 Report Posted March 1, 2019 That antenna is damaged. Just replace it regardless of any experimental results. They are not that expensive so new is the way to go. I just recently replaced a half melted transponder antenna. It was right in the path of the exhaust. It still worked but I didn’t want to have it fail on a trip. I also had it relocated to the left side of the belly away from the exhaust. 1 Quote
