Ibanza is active in a high wind area along the coast in Cape Town, South Africa. The predominant wind direction is South East and somewhat corrosive. We are now placing orders of TP400's to cut out the corrosion on the antenna pole mounts. It will also assist us to align the antenna more precise. This will enable Ibanza to build its MW backhaul without having to replace antennas every 3 years. Attached photo shows rust on 34dB antenna after 9 months.
