CX310A CX310 CX-310A Diamond Original Heavy Duty Wideband Coax Switch

Perfect for amateur radio use. I

The 3 way switch has quality fit and finish. With 3 coax leads from different antennas, connected to the switch, I did not notice any cross-talk. It does change the SWR a little bit, but one could adjust for this quite easily.

I use this switch to connect 3 antennas into the input of my tuner. Heavy duty and solid.

Quality product, still made in Japan. If you need to switch freq, above 500 MHz, get the one with the N type connectors. This is the one with the SO239 sockets to switch PL259s. Great product, Recommended. Albert EI7ii

I like the fact that the contacts are very strong and make really good contact. The ports 1-2-3 on this switch have very high isolation and cannot inadvertently make contact to each other unlike another brand offering thats on the market, which means that when using this switch to select different radios for instance you can rest assured that one radio port will not connect with another radio port and fry the other radio. This fact alone made me remove all of the other brand switches I had in my ham shack. Bottom line, this is an excellent switch!

Like I do with every antenna switch I buy I opened this one just to make sure nothing was loose or out of alignment. This is one well made heavy duty antenna switch. Very positive connection to the center and solid common ground. Will easily handle up to legal power and should last for years.

This is a well built unit. I highly recommend this over a MFJ unit (cheaper). The MFJ just puts way too much reflected power into the antenna system. With this Diamond, I dont see any negative impact.

Amazing quality. I was surprised at how heavy it is.

Replaced the same switch which I had had for several years when the contacts in position 1 became intermittent. I use four of these.

seems quality built, high power. Only complaint is price.
