At the moment I have a fixed GPS
unit (Numbers not pictures!) with an external aerial fixed to the aft toerail. I don't use it (I have never bothered to learn
)......instead I use a couple of handheld GPS
units (each of course with internal aerials).
Now, as part of coming into the 21st century
, I have the opportunity to acquire a 2nd hand Chartplotter
- with an internal aerial and whch will live in the cockpit
My initial thinking is to simply remove the external aerial fixed to the aft toerail (It is kinda in a vulnerable position) on the basis that internal / external aerial all same same and one less thing to go wrong / get damaged...........but I thought I would check here first as to whether the external aerial would give me something I don't know about..........
