Figure 2: Typical installation components
In a typical installation the RFI-148/900 250 will be housed in a weather-proof structure. Inside the weather-
proof structure a 2 m EUPEN 5092-HLFR cable will connect the antenna port of the RFI-148/900 250 to the
input of a band-pass cavity filter (CV1417-0111-11 for RFI-148 or CV9296-0511-11 for RFI-900) . A 5 m
run of LDF4-50 cable will connect to the output of the band-pass cavity filter, exit the weather-proof structure
into the input of a Huber+Suhner 3401 series lightening protector mounted on the outside of the weather-proof
structure. A 50 m run of LDF4-50 cable will connect to the output of the Huber+Suhner 3401 series lightening
protector, run across to a 30 m antenna tower via a cable tray, then run up the tower to an antenna (COL36 for
RFI148 or COL806 for RFI-900) mounted at the top. The installation is completely fenced off and secured
with lock and key.
