If you have the patience please bare with me as I'm hoping to learn I was trying to figure out what use if any could be made of a current measuring device located at the antenna feed point. There's an article in the Feb 2009 "QST" titled "Keeping Current with Antenna Performance", by Eric, KL7AJ, that will answer a lot of your questions about the benefits from measuring the RF current. Here's a tidbit for you. Put a Bird wattmeter at the antenna feedpoint and set it to indicate reflected power (power rejected by the antenna). The maximum radiated power from the antenna will occur when the power rejected by the antenna is at a maximum - assuming the feedline/antenna configuration doesn't change. Present that fact of physics to your license preparation classes and see what happens. :-) -- 73, Cecil, IEEE, OOTC, http://www.w5dxp.com |
