The antenna wire should now stick out to the front or to the rear of the unit (e.g. VT335 has a front hole) just like shown in the picture. Do the following for both main and auxiliary antennas:
1. Put a washer on the end of the antenna wire thread.
2. Screw the nut onto the antenna wire thread to the maximum with your hands.
3. Now use a wrench to tighten the nut
Do not tighten the nut on the thread too hard!
4. Screw the antenna to the end of the antenna wire thread.
