Steve 90 Posted September 16, 2007 Share Posted September 16, 2007 As long as I keep the screening intact and use screened connectors can I shorten the coaxial lead on my Garmin GPS ariel? I am aware that you are not able to shorten coaxial ariels on a CB as it will effect the performance of the arial. I don't think there will be the same trouble with the GPS arial but I thought I'd just check. I really could do with shortening it somehow as there is about 5' of spare lead!

Highway_Star Posted September 16, 2007 Share Posted September 16, 2007 Yes, as long as you do a good job of putting a new connector on. They are a bit fiddly to solder/crimp being so damned small. I did mine with no bother, but I work with wee connectors like that day in day out. That's absolute baws about CB antenna co-ax, ideally assuming we're talking about a standard vehicle mounted whip type antenna? Ideally you want the co-ax as short as possible to keep losses to a minimum. Quote Link to comment Share on other sites More sharing options...

I don't think there will be the same trouble with the GPS arial but I thought I'd just check. There is a very big difference between a GPS receiver and a CB transceiver. If you have the correct connectors and have the means to attach them properly (crimp or solder) there should be not problems. Problems occur if the arial is used for transmitting, as you would want a perfect standing wave ratio, so that the energy isnt feed back into the transceiver. So if you were to shorten a coaxial for a transceiver you would want to adjust the standing wave ratio afterwards. (This is done by using a SW-meter and adjusting the arial length - usually a couple of milimetres) Quote Link to comment Share on other sites More sharing options...
Steve 90 Posted September 16, 2007 Author Share Posted September 16, 2007 Cheers for that guys, I will get a plug and shorten it! Quote Link to comment Share on other sites More sharing options...
