The MFJ-330 gives you a much stronger HF signal when you use a magnet mount for HF and a direct ground wire connection to your vehicle chassis is not available .  Lets you talk farther and longer on 40-6 Meters mobile.  Use two or more MFJ-330 for 80/60 Meter operation. MFJ's magnetic ground pad provides an effective ground required for HF mobile antennas when a direct ground wire is not available.
