Thoughts about how to protect the SPE EXPERT 1K-fa from static or lightning desaster

Some years ago, before the SPE EXPERT time, I used a manual tuner for tuning my antennas.
I have a lot of antennas, and is doing a lot of new antennas, for test and fun, and my TUNER YEASU FC-301 have only room for 3 PL-connectors,
so there is also a lot of pulling OFF and ON these connectors.

So one day I desided to make a ANTENNA-SWITCH-BOX - this BOX is described here...
Just now, the box is placed on standby for some later use.

So now...
How could I use this to protect my SPE EXPERT 1K-fa ?

This could be an OPTION:

My SWITCH have 5 ANTENNA-OPTIONS.

When the EXPERT is with NO POWER, it is by default
connectet to antenna 1, so Antenna 1 have a 50 OHM load.
No power to EXPERT = NO ANTENNA to FT847 or EXPERT.

With POWER to EXPERT, BAND selected, I still have the OPTION to switch ANTENNA-SWITCH to GROUND.

Fast and effektively!!!
NO cabel OFF and ON.
Just turn the SWITCH when you live the shak.

BUT...
I lose the power of EXPERT to do the antenna-selection itself.
