Well Dick, the man asked for a QUICK and EASY way to build an antenna for
50 mHz and what I gave him was about as quick and easy as it gets,is
effective, and has the bonus of being of almost zero cost. Not everyone
wants to mess around with formulae, interesting as the activity may be.
Someone else has done the homework, why reinvent the wheel?
Cheers,
Bob VK6BE.
