Antenna Switch


  • Antenna switch with 8 inputs by 6 output remotely controlled.
  • Aluminum cabinet painted in the dark gray color, having UHF type (SO-239) for the R.F connections and DB-25 for remote control.
  • All antenna inputs are switched to ground when not in use.
  • When the power are switched off, all antenna inputs are routed to ground for protection purposes.


Specification:

Size:

Width 29,3cm - Height 5,2cm - Deep 39,7cm

Power Supply:

D.C. 14 Volts + or - 20% drain about 100mA

Max. SSB power allowed:

5000 Watts P.E.P. with S.W.R. equal or less than 1.7:1

Frequency of operation:
D.C. to 60MHz
Time delay to switch:
Equal or less than 50ms (exchange forbidden during TX)
Insertion loss:
Equal or less than 0,1dB
Port Isolation worst conditions:

-64 dB -> 50.2 MHz (6m)
-68 dB -> 28.8 MHz (10m)
-71 dB -> 21.3 MHz (15m)
-75 dB -> 14.2 MHz (20m)
-80 dB -> 7.2 MHz (40m)
-86 dB -> 3.8 MHz (80m)
-92 dB -> 1.8 MHz (160m)

Port Isolation worst conditions measurements:

RX 1
RX 2
RX 3
RX 4
RX 5
RX 6

Connections suggestions:

Eight antennas, one or two radios.
The switch AS-86F receives the signals from eight antennas selecting one of them for each radio (six of then), leaving the others not in use, shorted to ground. In the case of power supply disconnection, the radios became free and all antennas are grounded.
