ECM carries nearly every conceivable combination of adapter. So tell us what you're looking for. Let us know the frequency (MHz, GHz) and our knowledgeable staff will do the rest. We go one step further than most distributors by offering a wide range of RF and microwave coaxial connector adapters from several manufacturers to meet your needs. When superior quality at higher frequencies is critical, our hand picked group of US manufacturers is available. When cost is an issue, we offer very affordable low frequency adapters from offshore manufacturers. And when materials are a factor, we can deliver very high quality stainless steel adapters up to 65 GHz or basic brass for your everyday needs. Tell us the connector series, sex and quantity and remember to mention the frequency range of operating if you know it.
