	That was a misprint.  The antenna is 33 ft tall.

	The person I bought the MFJ-1793 from told me
	he ordered an extra stand-off insulator, rod, and
	coupler from MFJ to tune the side stub to 30M.

	If I had any influence with MFJ I would  tune
	the attached side stub for 30M instead of 20M.

	That is unfortunate.  This looks like a good design
	both electrically and mechanically.  Guess I need
	to get busy and set it up.   N4KG
