Multi-taps and Line passives are made of aluminum die-cast housing that is painted with a protective coating which can withstand over 500 hours of salt fog spray with no sign of corrosion. Rubber boots inside the brass F-ports help keep the multi-tap water tight. With its low loss characteristics the frequency response provides a virtually flat wave form through the entire 1 GHz spectrum.

Housing are tin plated and solder sealed, producing a high degree of anti corrosive protection along with superior conductivity.
