Which GPS antennas work well....

[Jdmagoo]

Just wondering which GPS antennas have been seen to work well with the v2 of the m4?

many thanks

Hi,

I am interested as well in the information which GPS antenna would be recommended with the M4?

The information is here. http://autoquad.org/

Read through the Documentation Menu to find a tremendous amount of information.

I'm using a DIY dipole antenna and this one from Taoglas.

Hi all
I tried asking this in the general section a couple of days ago...no help so here it is in a more sensible place...

I now have my much anticipated M4's ... But no GPS antennas ... I think I have the right base item to make a dipole but I haven't worked it all out yet...can someone pls guide with some pics....I remove outer plastic sheath to reveal braiding I remove braiding to reveal stiffish clear plastic molded over a conductor...dumb questions... 1. What items form the dipoles ... 2. Do I have to strip the clean inner plastic from the inner conductor....sorry very nube question

Matt, you´ve been pointed in the right direction twice.

I thought this image says it all, no?

Oh, forgot to mention that the active GPS ceramic antennas work best:

Christof is using it with good results:

The way I understand it is one wire of the dipole is the main wire you have in your picture. You still need to strip the clear insulation off. Then I'd twist it and tin it with solder. I'd also cut it to maybe a 3/4 inch in size. The other wire is made up of the shielding -- that's the wiry material that is all straggly on your wire. What I did was carefully removed the first layer of insulation. Then I had enough shielding that I could separate into a bunch of strands. I twisted those into a bunch and tinned that. Then I took two copper hook up wires and soldered them to each end. Then, I used shrink tube on all three ends. I used a lot -- two layers to stiffen the main wire and some to make a nice bend where the u.fl connector is. Finally, I used some blu tak to make the T junction a little more secure. Here's a pic...

Matt: the shield is the "second wire".
Look at the image I posted above. Left wire is the core, right wire is the shield.
