The upgrade of the SCRD Emergency Operations Centre Radio Station is nearing completion with the installation of a new set of commercial grade antenna to replace the amateur GP3's and GP6. We selected Comprod Inc. Dual wideband 144/440 MHzFolded Dipoles 3 single element antennas for data and communications. For improved simplex operations a dual element folded Dipole was installed atop the tower offering 5.5db gain. 1000 feet new LMR400 coaxial cable was used. The HF inverted vee was checked and new LMR400 feed line installed.
They are robustly constructed. 
Wall mounted using Unistrut channel 
All new LMR400 feed lines tidied up and rerouted to central busbar
Busbar and Polyphaser/Alpha Delta surge suppression - Duplexes still to be added
