The only issue I have found with my CF riggers is  GPS do not work at all. Gill

Gil, maybe your boats run too fast for GPS to track - just a little humor from your friend on the top half of our world!

If your running Futaba Fasst with R603FS it has two antenna's. One is inside the receiver. They both need to be working equally for best range.
If you have carbon lid or cowl it is best to open and remove the internal antenna and unplug it from the receiver and buy a second wired one to put in it's place and run them both above the carbon. 
 
This mod increases range considerably even if you are not using carbon anywhere.

. Where do you buy the antennas? Thanks , Jeff

I use this stuff for radio box lids, GPS goes right through it:

My first all carbon rigger built for SAW was lost due to the carbon.  It was the old antenna system where the whole antenna wire needed to be exposed and I had about six inches exposed above the boat lid.   At the time I did not know carbon was an issue.  This was about 20 years ago.  The boat ran into a gazebo at about 90 to 100 mph and was completely destroyed.  I could not find the engine but after much looking found it in a 55 gallon can further down from the gazebo.  I know most of us are now using DSM but like Daniel said......one of the two antennas are in the receiver with my Futaba receiver so it is still a risk for good reception if only using one antenna on a carbon hatch.

Carbon Fiber Twin. Notice on the pictures how far I run the antennas out the boat. Definitely dont want to lose the boat. I did a range check and found that not having the antennas out of the boat will lead to loss of signal. After that test my antennas are as high as I can get them.

Okay, now that I have been able to get back to a computer after six days away, let me add another thought to this thread.

I know everyone so far has talked about boats and radio boxes made from CF, and rightfully so.  What a few have mentioned, or hinted at, is a wood or glass boat that is lined with CF.  I've seen thread after thread where someone has lined part or all of a wood boat with CF to "make the hull stronger".  Maybe is does, maybe it doesn't.  I personally don't see the need for it but that's just my opinion.  What isn't my opinion is that the same issues that affect a CF boat or radio box also affect a wood boat lined with CF.  CF applied to a surface will block the transmitter's signal from that direction if the antenna is on the opposite side of that surface.  This means that the antenna would need to be above the surface with the CF applied, just like it does in a boat, box or under a cowl that is made from CF alone.

If I'm such an idiot, why does this thread exist to begin with?  Seems to me some here have questioned the use of CF, including the person that started the thread.  Let me remind you of what he posted:

I have heard of carbon giving radio interference. Never checked into it. As far as running carbon fiber radio box lids on a rigger, has anyone on here ever had a problem from using it? I would not think so with the antenna exposed . But would like to hear from people who have tried it. Thanks, Jeff Lutz

Some don't think about how laminating different materials together will affect the operation of other areas.  A heating/cooling system thermostat comes to mind, a good example of how laminating two different material together can affect things

. I personally don’t use carbon. I asked this for a friend who uses carbon lids and he has recently lost radio. The key question was about if people have or have not had radio issues when the antenna is exposed. Some boaters were nice enough to share their time and experiences and I did learn about how another antenna can be added to a receiver I’m currently using, which is very good info. Thanks
