Calcutta Posted March 31, 2009 Posted March 31, 2009 Can anyone tell me if there is any advantages or major differences in a G.P.S. internal antenna compared to a external antenna? Which should I buy? Quote
TommyBass Posted March 31, 2009 Posted March 31, 2009 Used to be that internal antennas had worse reception... therefor hindering your ability to recieve signals in certain areas as well as effecting your overall accuracy. Some newer more sensitive antennas I hear work better but I dont have first had experience with internals on depth finders. Personally I would still go with the external, it gives you an advantage of being able to place it directly over your transducer or wherever else you may like in your boat. Most likely will still get better reception being as its out in the open whereas built into your unit may have interference from consoles or other electronics. My external states it needs to be placed at least a few feet from the screen, not sure how they get by with that on internals. Quote
acar555 Posted March 31, 2009 Posted March 31, 2009 I would go with the external as well. If you do have an antenna problem with an external you don't have to send the entire unit in to get look at, just the antenna. You won't have gps but at least you will still have sonar. Quote
Calcutta Posted March 31, 2009 Author Posted March 31, 2009 I had a feeling that the external was better but I wanted some opinions on it .You know how good technology is nowdays I thought there might not be much difference.Thanks all. Quote
