[VHFcontesting] rover tech - coax

[Bruce Herrick]

I have to disagree.  UltraFlex is the way to go.  Remember that in a 
rover, everything moves.  UF will absorb some of the vibration that 
the rigid stuff will transmit to whatever it is connected to.  I have 
had failures of internal connections to antenna connectors due to the 
rigidity of LMR400 as opposed to something like RG213.  But LMR400 is 
superior performance wise.  There are always trade-offs.  UF is a 
good compromise.  You get what you pay for.
