I have for sale my 2m/440 split-boom Arrow antenna. I DO NOT have the duplexer. I purchased a different duplexer and had a lot of success with it, but I no longer have it. There is a cable that comes from both connector block, so all you would need to do is purchase a duplexer. I also have a couple spare threaded rods just in case any would break (they become worn out over time). $50 SHIPPED to CONUS. Outside CONUS will be more. Please email me at zack (dot) email@example.com with interest as I do not visit here often. Thank you!
