[Elecraft] K3S: Need SO2R Antenna Switch Recommendations

[Jim Brown]

Hi Dick,

The 4O3A 2x8 switches are quite good, have excellent isolation. The more 
expensive one has even better isolation and probably has a band decoder. 
The switching inputs can be configured multiple ways with DIP switches. 
I don't recall details, because my band decoders are built into my 
5B4AGN BPF kits. And Ranko is very good to deal with.

I'd like the SO2R Antenna Switch to have a built-in band decoder so the Band Data output from the  K3's ACC jack will do the switching.  I don't want an external Band Decoding unit for multiple reasons. So far, the only SO2R Antenna Switch I know of that has a built-in Band Decoder is the FLEX 2x8 Antenna Genius.  Please advise if there are any others? Thanks!
