[Elecraft] KAT500 in Bypass @ Legal limit

Hey guys,

I have a need for a while to use an automatic antenna switch on fully
resonant antennas.

The KAT500 works great with an interface to my flexRadio to change
antennas for me at specific bands.

If I keep the tuner in full bypass mode, but just use it as an
automatic switch, do you forsee any problems driving a legal limit
amplifier through its relays?

I know the manual states this tuner will handle 1000 watts at < 3:1
SWR, but my use-case is 1500 watts in full bypass at 1.2:1 SWR.

Kind regards,

W9PDS
