I work for a small tower owner in SW Louisiana along the I-10 corridor. We own over 30 communications towers. I am just noticing that tenants are now adding new foam dielectric cables, 1 5/8-inch, versus the old 5/8-inch or 7/8-inch. This change is dramatic to loading of the tower since pounds are now over 2000 versus the old estimate of around 800. How are tower owners charging for this change in equipment on the tower?
