@@Jimscoolstuff Thank You. I missed that. What gauge is that wire that goes up the mast? What is the power rating of that? Is there any ARRL chart for the diameter of that wire vs power?
@@Last_day_events I used #22 wire. The impedance of the antenna is 49 x 50 ohms. This is 2450 ohms. At 100 watts the current into this wire is 0.2 amps at the feedpoint and increases to a maximum of 1.4 amps at the quarter wave point. There are much bigger losses in the ferrite core than in the wire.

Nice design and excellent analysis of what can happen in ferite materials !
Thanks for your comment.
jim , good info. have you ever considered making a video feeding the endfed 1/2 wave with a lc tuner :)
How many watts were you using in your test?
The answer to your question is in the video at time 7:17. Thanks for your comment.

@@Jimscoolstuff Wow, that's a very big help to me. Thank you !
