ND | From the looks of it, you will need the "cone" that screws on and has a set screw to hold the antenna and the antenna.
The antenna that was just mentioned above with the coils instead of the hard plastic pieces will work just fine, they are both 5db gain antennas (two nodes)
The coiled antenna is located on the Trimble site under the mobile base station.
There are two different "cones" A. one for mobile base station and B. one for rovers
Warning: the coiled antenna comes with a "cone" that does not fit your antenna base (Pictured)
If you still have the "cone" from your antenna you can switch out the top antenna with the set screw.
Two things can happen
1. the antenna gets hit by a tree branch or shed door and snaps off (usually you will still have the cone and see where the antenna snapped)
2. the top half of the antenna backs out of the screw due to vibration (usually you will loose the cone and need to replace the whole thing (on the new one, lock tight the threads on the cone))
Your options if you still have the cone
Order the antenna for the mobile base station and replace at the set screw - Cost is around $50-$75
If you don't have the cone
Order a new antenna with the cord and magnetic base and all
If you want the more flexible top half, then also order the antenna for the mobile base station and replace at the set screw

does anyone have a source for the top half of a trimble RTK antenna?
