Topband: Switching Pennants

[DGB]

I am wanting a simple way of switching 3 or 4 pennants from the shack. 
Anyone done this?

Quote From K6SEE ... All four Pennants would be installed with their 
points all adjacent to each other.  Only one feedline would be necessary 
and only one
transformer would be necessary, with the high impedance winding of the 
transformer being switched to the feedpoint of the Pennant in the desired
direction ... 73, de Earl, K6SE
