Dosy SW-4 antenna switch

Post by HOUND DOG » Sunday, 02 July 2017, 7:16 AM

Is anyone using this dosy switch for a dual polarity yagi beam and is there any benefit to transmitting with this switch in the combination, Vert./Horiz. position? I presently use a Delta 1500 watt A-B switch.

Years ago I had the Dosy meter with the V/H/D/aux switch, I used it a couple times and never really seen any difference except for the SWR went way up. I never looked inside to see how it was wired to do the dual polarity. I think the delta switch is a much better choice, it not only has better separation of the coax but grounds the unused coax/polarity. Be sure to run a ground wire to it from a rod outside or a cold water pipe if they are copper.
