The specification discloses a system for mounting a communications antenna and
a solar panel on an explosion-proof housing that does not require the use of conduit
ports of the explosion-proof housing. More particularly, a mast couples to the
housing by way of a prescribed number of threads, the mast having a circular cross-section
and an internal cavity extending along its axis. Wires extending from inside the
explosion-proof housing through the mast couple to the radio antenna and the solar
panel. The void within the internal diameter of the mast not occupied by the wires
for the radio and solar panel is filled with a sealing compound rated for explosive environments.
