I have a 601XL all-metal airplane with an Icom A-200 radio, a RAMI com antenna mounted on the top skin and connected with RG-400 cable. I did all the installation myself. I have had this flying for 6 years now. It transmits just fine in the air. When I initially installed it, I would get comments that it was a bit garbled while transmitting on the ground. But it was always good enough to be able to operate out of tower controlled airports from time to time. Receiving wise, I hear just fine whether on the ground or in the air. Just this summer, I started to get comments from fellow pilots that I was totally unreadable while transmitting on the ground. It would become crystal clear as soon as I took off. Does anyone have any thoughts of why this could be occurring or any place in particular I should start my troubleshooting??

It sounds to me like a grounding problem... Maybe there is corrosion around the base of the antenna.
