[Mobile-Portable] Dodge Caravan with High Sierra

[Jim Miller KG0KP]

Grounding is everything in mobile mounts on vehicles.  However, I have a 
friend who cannot get his to work on some bands on his VAN and I am sure it 
is because there is too much metal close to the lower portion of the 
antenna.  First make SURE you are grounded well.  The receiver hitch will 
not provide a sufficient ground in itself and requires wire optimally from 
the antenna ground point to the vehicle frame.  Purists will tell yo to bond 
all metal panels of the vehicle but I have never done that and do not think 
it is necessary.  I have the HI-Q 4-80 and love it on my pickup receiver 
mount and on a home-made receiver mount on my car (not much metal near the 
lower portion of the antenna).  BTW, I use a 102 inch whip above the coil 
(yes it is tall, 13'4" at the top, works fantastic).

73, de Jim KG0KP
