GPS Express MCX Active Antenna 3m 90deg (TA070030)

Has a long enough cable to get to the outside of a steel roofed boat.

For first test, I put antenna on galvanised iron roof, sat under it and powered on. It quickly had a full screen of satellites and said 2m accuracy. (I'd never seen better than 3m). Unplugged antenna, and it immediately dropped all but one sat. I use it in-car to mark holes 10-20m apart, so has increased accuracy greatly. A good buy.

I bought this Antenna to connect to my Garmin GPSMAP64 ST and older Garmin GPS 60. I tested the antenna on both Garmins and it works well. The antenna provided better connection to satellites, it is nice and compact and seems durable. I am very happy with this product.

The GPS unit had no reception in the hangar but once the antenna was plugged in full signal a big improvement.

works really well in remote locations
