Often, we are asked about remote antenna switching units, and in the past have recommended a few.  In the past the Ameritron RCS-10 unit was recommended, and for a time we were a distributor for this line of products.  However, now that Ameritron’s future looks uncertain with the recent announcements from their parent company (MFJ), we no longer recommend those products as the future for service and support is uncertain.  One unit that I personally use is the DXEngineering RR8B-HP-P2, a high power 8-port model that is well constructed.  As of this writing, the current price for this remote switch with console is around $700, so it’s definitely something you’ll want to budget for.  The alternative would be to run all feedlines back to the shack, terminating into a manual (local) switching unit. This is not recommended as it adds cost (coax is expensive), complicates the overall circuit and clutters up the shack. 

There are other remote switching units available from other manufacturers, many of which have a good reputation for quality and durability.  I’m simply recommending the unit that I have firsthand experience with.  We have no affiliation with DXEngineering other than being a long-time customer and user of their many fine products.  I suggest you do your own homework to determine which unit(s) best suits your needs.
