StackMatch and 180 Degree Phase Wide Band Phase 

Shifter User W9AD

 

HI JAY

Thanks for the prompt delivery of the Stack Match II and the 180
phase reversal unit. I am very satisfied with their design and construction.
Both towers are not yet matched all that close but the results so far have been quite encouraging. Enclosed are a few pictures of the installation so far, still need to dress up coax cables and bury radials.

Listen to this MP3 file of W9AD on 20m AM recorded in Calgary Alberta, Canada by VE6CQ> W9AD20MAM.MP3

Also listen to the array on 75M AM. You can hear Dave switching the 180 degree phase shifter in and out while he has all 6 of the delay lines in giving a 135 degree phase shift to the system or -45 degree shift. > Steve/WA1QIX test.MP3
