mobile antenna ground loss

The bigger the vehicle, and the higher the mount, the lower the ground losses. The ARRL Antenna Book assumes ~10 ohms of ground loss for mobile antennas. I've found that 12.5 ohms is the lowest I can get for a 75m mobile antenna feedpoint. -- 73, Cecil http://www.w5dxp.com |
