Yes, it's difficult with that silicone rubber on the threads. I just recently had to re-wire a Furuno BBWGPS receiver/antenna due to a damaged cable where it exits the antenna. I had to use so much force with the strap wrench, I thought for sure the base was going to snap but the top finally started to turn and break loose. Quad antenna's are now used primarily in portable GPS receiver's due to the fact that they don't lose efficiency when they are near other conductive bodies like the microstrip patch antenna's do.
