[TowerTalk] relays for remote ladder line switch

Hello,

I am considering building a remote ladder line switch using W199X-12
relays, which are open frame DPDT with 1600V breakdown voltage between
open contacts, 2200V between poles and coil/contact.

I run with 100W power.

Does anybody have opinions on relays like those, experience with them,
or good experiences with other relays that you think I should
consider instead?

I am looking at switching between two lazy H antennas (one east/west,
the other north/south) and maybe some doublets for lower bands.

The plan is to have each antenna switched either to a 4:1 balun, or
to ground. Would it make more sense to leave the unused antennas
ungrounded, or discharge static through 1M resistors?

thank you,

Rik AB1KW
