[TowerTalk] antenna switch

[George Skoubis]

4O3A has an 8 X 1 and 8 X 2 switch.  They are Ethernet controllable (maybe the older ones weren’t but the ones on the website now have BCD and Ethernet ports.

I have a DX Engineering 8 X 2 switch and switch it via a YCCC MOAS II switch.  The MOAS II switch can be controlled over the internet as well but the programming may be difficult.  It can switch 64 relays so one can take care of most stations.  I haven’t measured the crosstalk but the switch works well with my VA6AM High Power bandpass filters.
