[Elecraft] [OT] Antenna Question

Rick,

It "all depends" on what you did not communicate.
Is the vertical resonant? What frequency?  I assume not resonant if a 
remote tuner might be required.
If the SWR is high, then the loss in the RG-58 can be significant if a 
tuner is not used at that base of the vertical.  The loss depends on 
frequency.

TBD height does not add anything to the question regarding efficiency.

In other words, there are too many variables to give you an intelligent 
answer.

Assume a less then 50 ft run of RG58 and at least 4 counterpoise being used in a portable situation with a telescoping vertical of TBD height.
