Whats a good place (US mail order) to buy rg6/cable/connectors 50 ohm RF stuff

I used to know a company that sold cables, connectors, adapters, etc, that shipped from the US had decent prices and wasn't chinesium counterfeit stuff. No waiting a month buying off Alibaba or ebay that's just flooded with BS stuff where after a month of waiting you find it doesn't work or is used. For the life of me I can't find it(sorry my eye sight sucks and using google isn't as easy for some of us). I probably clicked on it but didn't realize it. Sick of getting junk online from amazon and having to return it.

So I have a new place with access to a fourth story roof and want to turn it into an antenna farm. I just need a roll of cable and lots of adapters.

Antenna farm for what? (Just asking cuz video usually uses 75Ω, not 50.)

Anyhow, Digikey, Mouser, Parts Express, Radio Shack even...

I've never used it, but https://www.americanradiosupply.com/ seems promising.

You know that RG-6 is 75 ohm, not 50 ohm, right?

If you actually want 50 ohm stuff, try DX Engineering: https://www.dxengineering.com
