+bigbill6 Posted June 26, 2002 Share Posted June 26, 2002 will an ex.antenna help in heavy tree cover,does mag have ex.ant, is it worth it. Quote Link to comment
+Ranz Posted June 26, 2002 Share Posted June 26, 2002 The MAG-315 does not have an external antenna connection. You would have to use a re-radiating, which requires another external power supply. I would be kind of bulky in the field. The 315 has a very good antenna as it is. If tree cover is an issue then any external would have to break out from to trees to be effective. I think you are better off moving to a clearer spot for a reference. Works for me. Happy Caching; Quote Link to comment

White Rabbit Posted June 27, 2002 Share Posted June 27, 2002 Well, being cachers from Oregon, we see a LOT of caches in the forests. For the most part, if our Mag-315 is fully charged on batteries, it can usually do fine under the trees. We can usually get it to find 3 satellites without any real problems. Sometimes it does take it awhile to figure out where it is and where you're taking it, but sooner or later it figures it out. I wouldn't worry about figuring out how to hook up an external antenna. I am the Rabbit King, I can do anything Quote Link to comment
+mikedx Posted June 28, 2002 Share Posted June 28, 2002 Then what's with the Magellan offering an accessory (or is this what you mean by re-radiating): Power/Data Cable w/Bare Wires - 300 Series Power provided to your GPS receiver from an external 9-16 VDC source. Allows the GPS receiver to be connected to a differential beacon receiver or other types of NMEA devices. Comes with detailed instructions. http://www.magellangps.com/en/products/product.asp?PRODID=139 Quote Link to comment

You can use a GPS's NMEA output to feed data to a processor to combine the two signals and improve accuracy. The beacons are mostly in coastal areas for marine navigation. The reception of the GPS unit itself is not effected. Quote Link to comment
