WIMO Diplexer #22030 - 2m/70cm 100W

As a logical follow on I opted for a separate Diplexer for my Arrow antenna. I've choosen the WIMO Diplexer #22030.

 Here are the first, basic measurements done with the following setup:

• miniVNA^tiny
• vna/J 3.2.6
• 50Ohm terminator Mini-Circuits BTRM-50+
• 2 SMA-BNC adapters
• 2 50cm RG58 BNC cables
• Calibration done on 2xcable + 1xBNC-F-F

Transmission between Antenna port and 70cm port

2m port terminated with 50Ohm.

Transmission between antenna port and 2m port

70cm port terminated with 50Ohm.

Isolation between 2m port and 70cm port

Antenna port terminated with 50Ohm.
