RAS-4 Receive Antenna Switch
Receive only antennas are critical for success on the low bands. Unfortunately they only receive in one or two directions, and most are far too large to rotate. The RAS-4 allows switching of up to four antennas using RG6 coax, the standard for these types of antennas.
The RAS-4 is housed in a NEMA rated enclosure with a gasketed lid. A cable gland seals the control cable entry. Finally the internal circuit board has a conformal coating for additional protection.
Common mode noise pick up can ruin the performance of receive antenna systems. The RAS-4 isolates both the center conductor and shield of unselected ports. A bifilar ferrite choke further reduces common mode currents.
By default, unselected ports are terminated for 75 ohms. The user
