Thank you to all who have responded. Many good ideas. I am currently sitting at a wi-fi location in the hospital. When I get home today I'll look more carefully at all that has been offered.
My main hope at this point is that the puter will give me enough time to bring up F12. We will see.

It would really help new amateurs who want to build antennas to find an older copy of the ARRL Antenna book. There are too few explanations and too little data in the current editions. By old I mean say pre-1989. Cruise hamfest tables and Ebay, there are plenty available pretty cheap.
