Hey, Carl -

I don't know if I am understanding the instructions correctly. I take them
to mean that the 3' 9.5" antenna is attached to the end of the coax and
then you come back away from the base of the antenna 12.9" and splice in a
1.9" piece of shorted coax. If this is true, then working backwards from
the stub I find that the antenna is about 2.4-j73 Ohms. Seems a bit
strange for an end-fed half wave, but never mind that.



Oops! I forgot to include the velocity factor of RG58A. Using .73 would make
the antenna 23.9-j199 Ohms. But, this estimate is not really useful to you
and I probably should have left out that whole paragraph. Just ignore it.

John
