Hi. This allows any rain water to drain out of the metal shaft. Without that slot bored out, the metal base will hold water and the antenna will eventually stop working.
It provided a route out for the water, between leakage and condensation those antennas are very prone to collecting water. I pulled one down off a tower some years back and after we pulled top cap and drained, we got over a 1/2 cup of water out of it. Keep the water out and they are affordable and high performing antennas.
Nice quick helpful hint video M'Lisa
What was the purpose of the verticle slot that you bored out? I have the same antenna and it is water logged as well.

Roger that makes sense. I have a Dremmel tool with a cutting bit I will do that on mine as well. Thanks for the prompt reply and 73's DE KQ1USA
