Effective HF Mobile Antennas
If you are operating below 21 MHz,it is all but impossible to run a full-sized mobile antenna, so some sort of loading coil will be needed

ML-90 Vehicle Roof Rack Magnetic Loop Antenna
Highly efficient antenna, radiating 10dB to 14dB more than whip antennas. Equivalent to a 500 Watt transmitter with a whip antenna
Mobile on 136kHz
It's just under 3Mtrs long. It is mounted on the roof of the car on a cross member bolted to the luggage rails
Portable Vertical Antenna 20-30-40mt
The concept is to make the antenna self supporting and able to be broken down into small pieces for easy transport
Antenna Mounts
Thus the antenna should be attached in such a way to maximize what little ground plane a vehicle represents
