[VHFcontesting] Rover Tech: Mounting - Will this work?

[WBR]

JT,
    I'm not an ME but I thought that I would respond anyway.  The trailor 
hitch end sounds ok except, I would be sure to use some black dacron antenna 
rope for guys to the front bumper or other solid anchoring point.

You say that you want to use a ten foot mast and then on top put more hight. 
Don't forget that you need to stay below eleven feet over-all from the 
roadway.  I'm not sure that you really need ten feet of mast.  Just use what 
will get you above the vehicle safely, and use guy anchors to another part 
of the car.
Also, I think that some sort of shim between your mast and the steel rod 
would be in order to stop rattles.  Use something non-matalic.  Ferrous 
steel and aluminum don't get along well.

This is only my opinion, I am not recommending anything.  So the caveat is 
that you do at your own risk.
GL es
73,
Bill, WF4R
