Narrative:
I was working all radar positions combined in the tower cab due to the covid schedule. We had a priority handling aircraft land at ZZZ1 which caused multiple aircraft to be placed in holding/kept in the radar pattern. While this was going on I had a heavy increase in traffic volume. I based aircraft X to a 240 heading after an extended downwind; about 15 miles out at 020 MSL. Shortly after basing the aircraft I received multiple calls from aircraft and became saturated with traffic and transmissions. I realized aircraft X had gone through final and was headed towards a man-made obstruction with the obstruction height of 2;XXX feet. I issued a right turn to heading 050 to get them away from the obstruction. I started issuing a climb to aircraft X when I realized I had a VFR aircraft receiving radar serve at 030 directly about him. This caused me to cancel the climb and stick with just the turn. I then tried to turn the VFR aircraft so I could climb aircraft X but between my voice quality and the other aircraft on frequency he didn't understand my transmission. I believe aircraft X came within 3 miles of the obstruction.I believe working on the tdw (tower display workstation) display which is smaller than our normal stars displayed caused a higher complexity of traffic. I'm not really sure what could have prevented this event other than going back to normal staffing levels and working back in the RAPCON.
