this version of hub is new advanced mobile hub for signal booster antenna. signal reception is better in this version as it is shorted very slightly to make network smooth. because of its radiation managing pattern, it energizes the signal recieved from external antenna. the 220 k resistor maintains the up-down frequency and provides network good stablity.
