I doubt about using it for TX; I only want a switch for 2 antenna connected to my SDR, son only RX. Cheap option that does not cover SHF bands, but valid for HF and VHF with not much attenuation.
Billig antenn omkopplare.
Borde ha bestyckats med dubbelbranchig omkopplare, som då gjort att enheten skulle klara > 50 Watts effekt mot dikterade 10 watt. Skärmväggar med elektrisk bra kontakt till chassiet=jordplanet. HF-egenskaper får mätas senare.
