Tuned MFJ-1024 Active Antenna

Hello Group

I have been wondering if it might be an advantage to remotely tune
this active antenna using a varactor? The remote unit uses a 40673
dual gate mosfet followed by a 2N5109 npn vhf/uhf transistor which
feeds a 30 turn bifilar wound 4:1 balun. Then rg58 to the control
unit. The whip is 58"/1473mm in length. Any thoughts on this? Thank
you.

Richard
