The 144 / 432MHz prototype diplexer was soak tested and is still running on the APRS Igate MB7UBN after 3 years continuous service. The Igate runs 24/7 providing APRS coverage to a large area of NW England around Bolton, Manchester and Warrington. The diplexer with it's original grey case is in the bottom right of the photograph directly connected to the Heliax coaxial cable from the dual band colinear antenna.
