NGP antennas use the coax for a ground plane and the range is limited perhaps very limited.
Here's something to try as it worked for me. Since I didn't know how the antenna would preform on my last rig I did the following:
1. Pick a reasonable location.
2. Mount the antenna on a board and strap it to the rig at the location - Note I did not drive the vehicle.
3. Connect a large wire from the antenna ground to the nearest frame location which for me was under the rig.
4. Make contacts note the signal level and ask them where they are located.
5. Run the engine and check for any engine electrical interference.
6. Mount the antenna and run a short heavy ground wire to the frame.
This method worked very well to help me determine where to place the antenna and I had close to a 4 mile range. Basically the steel in the MH became the ground plane. The MH house was steel framed and no doubt this helped with the antenna radiation. Aluminum and/or wood framed rigs wouldn't do as well.
Try it and see if it works for you.
