- six (6) antenna port allows switching of independent antenna for HF and 6m band
- heavy aluminium case thickness 4mm (158 mils), IP 66 provides high level weather protection and RF proof capabilities
- SO239 UHF or N teflon™ / gold pin connectors used
- 10kV surge strength, high power 16 Amp boxed relays made
- stub compensated microstrip PCB architecture assures lowest SWR and insertion loss from 1.8 to 60 MHz
- built-in surge protection
- compatible with all 12V source driver band decoders
- connects directly to micro Band Decoder™
- top cover screws protected against loss (very useful at tower)
- easy wall or tower assembling thanks to special galvanized heavy double C-bolt, which allows using various diameter of the tower tube
- unselected antenna ports are grounded
- without power all antenna ports are grounded
- each device is individualy trimed and tuned for best performance

SWR and isolation :
| Frequency | SWR | Insertion loss | Isolation |
| 1.8 MHZ | 1.00 | < 0.01 dB | > 80 dB |
| 14 MHZ | 1.03 | < 0.01 dB | > 64 dB |
| 28 MHZ | 1.07 | < 0.02 dB | > 58 dB |
| 50 MHZ | 1.12 | < 0.05 dB | > 50 dB |
values are typical
all measurments were performed with HP8714B network analyzer
- SWR is measured from input to any antenna port
- Isolation is measured from any antenna port vs. radio port connected to one 50 ohm terminated antenna port
