Power splitters are used to combine 2 or more antennas on 1 feedline

HF VHF receiver diplexer
The design is relatively easy, a back to back low pass-high pass filer system with a 50 ohm impedance throughout

Stacking with homemade Power Splitters
The basis of the power splitters-combiners is a construction of a square tube for the outer conductor and a round tube for the inner conductor
