Cut GPS Antenna Wire??
On a simple BNC type GPS antenna, you can cut and shorten or lengthen. Be
aware that there is usually 5 VDC or in some old equipment 12 VDC run up the coax from the GPS display to power up the electronics in the antenna sensor unit. The GPS frequency is usually downconverted before going to the coax, so loss is not a real big concern. There are other GPS sensors than the coax type, such as NEMA and Raymarine SeaTalk. Once again, be sure power has been turned off to the cable before making cuts, splices, etc. Opening the Antenna and looking for a BNC, SMA, or SLB connector is a good idea, but it is a toss up on what to expect, a connector or solder to PCB. Be sure to water proof your connection if you are in the Pacific NW to keep the moss out. LOL Doug K7ABX "Chuck Tribolet" wrote in message ... Shortening is not a problem at those high frequencies. I wanted to shorten the cable on the antenna to my Garmin 162 to eliminate a bunch of extra cable. I called Garmin. They said no problem, but it would void the warrantee on the antenna (but not the GPS) because they had no control over the quality of the connector and its installation. Since the unit was already off warrantee, I went ahead and did it. Works fine, signal strength is a touch stronger. -- Chuck Tribolet http://www.almaden.ibm.com/cs/people/triblet Silicon Valley: STILL the best day job in the world. |

Cut GPS Antenna Wire??
Boy we have beat this one into the ground, huh NG. Just cut the cable and put
a connector on it. Don't worry about all this other stuff. If it doesn't work then you most likely shorted it. Just ohm it out prior to tunring it on. NBFD - Its done ALL THE TIME. If it worked before cutting it, it will work after you put a connector on it (taking in consideration no shorts) Brian Remove NOJUNK from Email for responses via email. |
