I have 2 other GPS devices already on the splitter, so there is really no need for any DC current to be passed as the splitter will just sink it. I just wanted to build an extra measure of safety in there sinking the 12V before the splitter *incase* the other 2 GPS devices are turned off or something happens.
Yes I'll probably plug in the NTS and check the power on the antenna port, if it stays at 5V then I can at least use it temporarily to ensure that it's working and everything. I'll look into some of the mini-circuits stuff on eBay and see what I can find. I probably won't buy / build anything until the unit arrives. I might be able just to desolder a component and sink the 12V internally before it gets injected to the RF signal. But I don't want to cut any PCB traces or do anything that is irreversible. Thanks for all your input guys and various solutions. :) I'm surprised nobody said get a 12V antenna... lol. Does anyone have any spare outdoor mast style they would sell (cheap)? I remember I saw some on eBay a while back, I'm sure more will pop up eventually.
