[Mobile-Portable] Mobile Antenna Grounding

[K7fe at aol.com]

Owen,
The RF on the outside of your coax is not standing waves it is RF pickup  
from proximity to the radiating portion of your antenna.  Pickup may be  more 
prevalent with a poor ground.  Standing waves result from an  impedance mismatch 
between your transmitter, coax and/or antenna.  The  efficiency of most HF 
Mobil antenna's is so bad that RF pickup on coax is  insignificant in comparison. 
 Anyone who owns a network analyzer probably  knows all of this anyway.  I'm 
jealous, I use to have to borrow one from  work.
 
My antenna is a home brew bug catcher that I describe on my QRZ.com  Bio.  I 
built it to handle my amplifier that had melted down several  commercial Mobil 
antenna's.  I am considering the HI-Q 4 or 5 inch motor  driven coil for 
convenience of band changing.
73,
