The Diplexer is already built-in which requires only one connector each for the combination antenna and the feed-line.

Features: HF-VOX, max. power handling 100 Watt, separate FETs for 2m and 70cm band as well as steep band pass filters; this avoids the well-known intermodulation effects and does not exhibit any broadband receive functionality. Selectable voltage feed via coax cable or separate line.
