he RV/Trucker cellular antenna is a versatile antenna that works great on RVs, trucks, cars, boats, homes, or almost any other application. Its main benefit over our other dual-banded antennas is its integrated spring and 5/8" by 7" threaded mounting rod which is designed to span roofs with large gaps such as the attics found in most RVs. For installations through roofs without an attic we provide instructions on cutting the mounting rod - it is brass and cuts easily. Works on any surface - metal, fiberglass, wood, etc. (no ground is required).
