Common grounding point is the secret.

Not true.

Use only one antenna. A roof mounted 16V style, or a
regular fender mounted one. 

It requires extensive knowledge and test equipment to
make multi antenna systems work. If you don't, you run
way more risks to harm the radio signal, than to
improve it.

Make sure that your antenna cable is in good
condition. That it is not nicked, or has sharp bends
into it. If so, it has to be replaced, as it will no
longer carry efficiently the radio signal through it.
Simple electrical continuity with a VOM is not a good
test for any radio cable/antenna. Make sure that
connectors are factory made. Home made connectors,
splicing, twisting wires, will definitelly harm the
signal.

Cheers.
