The tall ones are multi-element antennas. The structure that I've
mostly been talking about is a vehicle-mounted shelter that doesn't
have the ISO pockets, so adding railings or stanchions would take
modification that requires authorizations to go way up the chain. The
roof is an aluminum honeycomb/sandwich material, so welding isn't an
option even if we got the ok. Our PTB doesn't even want to go the fall
arrest route, due to adding requirements for training, gear
inspection, etc. which is why we're probably just going to remove the
antennas from the roof.
