1. Can raising the height of my outside antenna about 1 ft make any significant difference? 2. What is a full proof way to test the noise in your setup site?(trying to determine whether or not I need a filter) What are deciding factors that would indicate the need? 3. Does anyone recommend the Glamos antenna tester and/or is there any device that can be bought on Amazon that can give the same desired readings (possibly cheaper and more available since almost everything is in EU or ~$325dollars when trying to purchase Glamos) Thanks Reddit!
