Getting your antenna in the air can sometimes be challenging. Not all of us have unlimited real estate and 120 foot towers at our disposal to hang any radiator on that we please. We all have to work within the confines of our situation, meaning limited space, property restrictions, access, or even budget. KB9VBR
