Buy an Antenna Tuner for the radio corner

MFJ-993B is interesting - remotely controlled automatic ATU with antenna switch. MFJ-993RC remote control can be used to switch antennas from the shack. 300W power handling.

LDG RT-100 is a simpler waterproof autotuner, albeit only with 100W power handling.

ww suggests an SGC Smarttuner, second-hand.
