Deluo GPS antenna modification help

**antimatter** · 03-17-2005, 02:02 PM

Can anyone point me to a tutorial on how to add an external antenna hookup to my GPS reciever. I plan on getting an external tri band antenna and will want to hook up my Deluo GPS module to it. Unfortuantly they don't have antenna hookups

I am very comfortable with a soldering iron and fabrication/electronics.

I just want to see some pictures of a mod before i get started.

If anyone has passed by such a tutorial please pass the info along my way.

Thanks

I have got a old unit from them its a serial port type

I had problems getting a lock in my car - I kept moving it around
and no luck - I thought about that it had a magnet, and got a flat
piece of metal - I stuck the GPS unit on top and BAM I got 4 to 6
sats locked

I have it mounted under my rear window as close to the glass
as I can - its under the carpet on my rear shelf mounted to a
square piece of metal - the metal is about 5 inches square

If you can some how replace the antenna you could try this but
its ugly

THanks for the reply. I think i am just going to hack it open and take some pictures. Maybe someone can identify what part is the antenna if i cant. I have an antenna in mind

yes take some pictures, i'm sure we can sort out what needs what. I attached a external antenna to my radioshack GPS that was not designed for an external antenna and it worked great.

Thanks jcdillin. What i need to do is get an FME connector to hook it up to my GPS antenna that i am getting. I will try to take it apart this weekend and post pictures

so maybe just get a piece of coaxial cable with a fme connector on that and solder the other end to your gps, that would keep the amount of connections low

Yea, that is pretty much the idea. I just don't know what to connect to what

So i finally got the GPS antenna that i have been waiting for and I took the gps out of the car opened it up and took a couple photos.

Any idea on where i need to attach the leads too?
