Derek, my concern is mechanical, rather than RF. Many moons ago, I received a brand new DB224 for the club, which was soon to be installed at a new site. Observing the fine new aluminum elements, I saw that the drain hole was not in the bottom of the loop, but rather up an inch or two from the bottom. My infallible wisdom dictated that a drain hole should be at the bottom. So, I made it so.
A year or two later we were getting a lot of noise on some signals on the repeater. Inspection revealed that three of the four dipoles had physically broken, you guessed where, right where I had drilled the small drain holes. :( Having said all that, filling the hole with a good stainless bolt like you did may prevent that kind of mechanical failure, I don't know. There are apparently stresses and fatigue going on there that I don't fully understand.... Laryn K8TVZ --- In Repeater-Builder@yahoogroups.com, "Derek B.
