80 m compact loop - progress report
Most people put the series tuning capacitor in the top side and the feed
point at the bottom side. Since the capacitor, motor, and their mounting hardware is quite heavy, I am currently planning to do the reverse of the above, i.e., tuning capacitor at bottom and feed point at the top. It is not clear to me if there is any difference between these two configurations. John, N9JG "Frank" wrote in message news:6XQLf.5171$M52.5078@edtnps89... [snip] Note that John mentioned he is using a gamma match, and tunes out the reactance of the loop on the opposite side. The diameter of the loop is a nominal 20 ft, so it would make the most sense to tune, and feed, the antenna on the two vertical elements. My model is 30 ft at the top, and 8.272 ft at the bottom, so even with the reduced height motorized tuning makes a lot of sense. I am going to model a gamma match, and opposite side tuning cap, so will update the code this weekend. [snip] |
