May I ask the experts if it is reasonable to use a splitter in the KLN89B coax line to get GPS signals to the Garmin 295?

In the past I have been told that you should not use a splitter on a GPS antenna, and you certainly can't use the same type of splitter that you would on a VOR antenna. However, I see that there are devices on the market specifically for splitting GPS signals. (Check out http://www.spectracomcorp.com/Home/Products/Antennas/8224GPSAntennaSplitter/tabid/147/Default.aspx or http://www.rfglobalnet.com/content/productshowcase/product.asp?docid=d7b0c7f7-98a4-4658-889f-1ecf5c9c7629). Many GPS antennas are active antennas, like the KA 92 normally specified for the KLN89B. Assuming you're using an active antenna with the KLN89B you need to make sure that the splitter will pass DC power from the KLN89B to the antenna while blocking DC to the Garmin. I've never tried these products so I don't know how well they work. I'd want to do some more research before I tried it. Hopefully someone else on the LML has some recent exerience in this area.

May I ask the experts if it is reasonable to use a splitter in the KLN89B coax line to get GPS signals to the Garmin 295?

If so, can anyone recommend the type of spitter to install?

Thanks
