[TowerTalk] Measuring radiation resistance of a vertical

[Rick Stoneking]

Is it possible to measure the radiation resistance (only) of a vertical with 
either an antenna analyzer or some other type of readily available piece of 
equipement?  The converse of this is how do I measure the loss resistance of 
the antenna?  I am trying to determine how effective my radial system is and 
how efficient my antenna is.

Thanks,
Rick
