Sorry for the necro-post, but I found a replacement cable
it's the IPEX 20453-030T to IPEX 20453-030T micro coax cable
bought one from here:
https://www.quadrangleproducts.com/products/sgc1103-6/ for $42
It is quite a process buying from quadrangle, though, you basically need to request a quote, and they'll give you a quote and a code that you input into a buy order form, and they'll call you via phone and ask for your CC info cause they don't have an online checkout service, and you may have to be apart of a company/business/college to purchase from them (not 100% sure but in the buy order form a company name is required)
