To give you an idea on how it can be done, I have put a quick screen dump 
(in PDF format) for downloading at
http://www.hard-core-dx.com/nordicdx/antenna/wire/beverage/remoteswitch.pdf

I use it to control three remote beverage antennas, but should be easily 
converted to remote switch of any antenna.

Not a lot more details but the schematics. Those details that I have are in 
Swedish, and I don't feel like translating all that at this hour (past 
midnight, local time).

I have added a second PDF, showing how I connected the stuff.
