Sorry for the off topic post, but I figure there are lots of people here who would know what to do with this. It's a 100 ft spool of unused 3" Andrew Heliax, HJB-50B, RG-322/U. I'm downsizing my business and no longer have room to store it. It's on eBay item number 113668741992. If anyone has a suggestion about where I should list this please let me know. if you are interested in purchasing it at a bargain price, PM me. It has a standard 3-1/8" EIA flange on both ends. I need to vacate my current location by August 31, 2019.
He has a "buy it now" price of $650, but you can likely make a deal with him directly. I cc'd him on this email.
