That was used as a ham antenna one night (with permission) and it did not work as well as hoped. PS;TNX for moving the post, much better choice.
The reason that I made that snide remark is because the goals for building the best antenna to get a signal from the AM BCB transmitter to grandpa's receiver sitting on a kitchen table 25mi distant are not optimum for building an antenna for 40meters, even though a lot of hams believe that...
Here are some good Part 73 lessons for Part 97 ops... 1) The use of ball gaps or a similar configuration is important for discharging static build up on non-grounded antennas. Placed at the base of a tower or closest point to ground of an antenna will give a low impedance path to ground for an induced or direct lightning strike. The addition of a single turn loop in the feedline will make the feedline appear as a higher impedance. 2) Position tuning inductors in different planes to minimize interaction. 3) A Port-A-John can make a great enclosure for your 630 meter antenna tuner once the blue water is cleaned out.
