Nathan, don't forget that the tower with no antennas has wind limits so don't assume no antenna or very small antenna means no design/engineering considerations. If you are not subject to significant

There is an exponential extinction coefficient that governs penetration of RF currents below the surface of conductors. Lower freq means greater depth of penetration or in other words how thick is th
