Wow. What a product! I had such severe RFI from the Ultimax DX Extreme 72 footer that my rig and home were going crazy. This is *NOT* the fault of the antenna but the nature of an end-fed design. The choke was an necessity. When I purchased this from Ultimax, I was really impressed with the quality of construction and ease of indoor installation. Once tested, the RFI problem was instantly eliminated. My questions were quickly answered by telephone!

I purchased this with my EFHW, so that my coax does not radiate as the antenna and to prevent RF from tracking back into the shack. Great product. Well made.
