NOTES:
1. Input power with 1.5 max output load VSWR. Power handling is reduced when used as a combiner. Consult factory.
2. To equalize the phase at all five ports, add an additional external line length to J3 and J5 equivalent to 1.2 cm of air line, and add a line length to J4
equivalent to 2.2 cm of air line.
