Coax adapters from US brands and US-based sellers
Amazon ranks by what sells fastest, so a coax adapter from an established brand gets buried under cheap imports no matter how far you scroll. This page lists the US brands and US-based sellers for coax adapters, so you can start from the ones worth trusting.
We read each seller's registered country from Amazon's own published seller info. We don't claim anything here is manufactured in the US, only that you're buying from a US brand or a US-based seller.
