Henry Radio is a major distributor for Tohtsu coaxial relays. These are very high quality, Japanese manufactured coaxial relays that are typically used as antenna relays for all kinds of RF switching. We have sold the products for more than 30 years and have found them to be a reasonably priced reliable solution for RF signal switching. There are a number of different configurations and coil voltages available. Please contact us if you don't see a relay here that meets your requirement. We stock many of Tohtsu's models for immediate shipping and have orders working with the factory regularly.
