I know a really good company that's called adactus. You can buy antennas, connectors and a lot of other stuff that's really good. I've been there a couple of times and bought different things. I mainly bought items for my new boat. I needed a really good gps system and then I heard of this place and I thought it was really good, so I went there and bought some stuff and installed them on my boat and it works really well! So I think I'm going to go back there some time in the future actually, it's going to be really cool! I'm thinking of buying some other equipment.
