We now have both consumer and commercial non-penetrating roof mounts (NPRM) in stock. Pictured above are the consumer models with pyramid base and designed for our 8′, 10′ and 12′ antennas. The commercial models are designed for our 10′, 12′ and 13.5′ antennas.
Each modular tray measures 4′ x 2′ and weighs just over 100 lbs and can be assembled in either a “T” or “I” layout. Each tray can hold up to 8 concrete blocks (consumer models) or 9 concrete blocks (commercial models). For structurally strong roofs, you can add a second level of concrete blocks to minimize the number of modular trays required. For weaker roof structures, we recommend using additional modular trays to spread out the load and take advantage of the principle of moments (i.e. Archimedes discovery of the lever) to reduce the total ballast weight.
We recommend using 16″ x 8″ x 8″ (each weighs 36.5 lbs) concrete blocks as ballast which can be purchased for $1.61 from The Home Depot:
